I want to install REV 1116 dual springs on my heads.
This is for a 422 stroker.

Cam is 236/240, 601/609, 114 LSA.


Would love to hear from others that have this springs on a similair cam setup without problems.

Thanks,
Michael

I've donme several without issues (yet) but have a freind who recently broke two springs this past week.

I am going to go to a larger diameter set up but am looking for answers on the proper combo. I will post as I gather parts and configure.

I have REV dual springs on my car currently. 2nd set. My first set I installed last august, after about 2600 miles, I had 2 springs break. I got a new set and replaced all the springs. I've put 3000 miles on that set so far and have had zero problems (*knock on wood* <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" /> )

This was on a 224/224 .581/.581 112lsa cam. Your cam profile looks rather large to be using stock untouched heads. I would have the spring pockets machined out to recieve a set of 1.4"+ diameter springs (comp 987's, etc). If I ever had my heads off the car, I'd have mine cut.

Now I know for sure, that I donīt want these springs on my new heads!!!!!


We called REV and hereīs what came out:
Malibu Vette (9:44 PM 1/21/2003): I talked to the manufacturer of the springs yesterday. He was very forthcoming and helpful. The springs are not designed for the kind of lift we are using them on. He is truely only comfortable with lifts of .550n or less. He suggested a larger diameter spring which would require machining the head. I am investigating this option. REV also told me they will have a new verion of the 1116 out in about 45 dats made with a different material. I hope this info helps.

Hello All,

I am a Technical Representive for REV Racing Engine Valves in Ft Lauderdale, FL and this situation has recently been brought to my attention. There is some confusion with the techical specs on the valve spring that we offer for the LS1 application.

1- The spring is actually good for .610" of cam shaft lift maximum (this figure includes a safety margin)..

2- The springs installed height is 1.800-1.840" and provides 135LBS on the seat, and needs to be used with REV Locators and REV retainers.

3- The spring in question for this situation was a REV inner but not a REV outer thank GOD for that inner.. we do not know where the outer came from. (THIS IS FACT)..

Any other questions or concerns Please Call our techline @ 800.398.6348

Thanks for the input!

Now would you say that the 1116īs are a perfect fit for my needs??

And whatīs about that theses springs have less install hight with the REV retainers, so that A&A makes special parts to get them installeed higher and Mike Norris makes modifications , to fit them, too?!?!?

Thanks, Michael

Yes Sir,

As a matter of fact the VS1116 are perfect if installed properly, that is one of the biggest issues with this application, if correct installed heights are not achieved.

We have no idea who A&A or Mike Norris is? Please fill us in so that we can call them and discuss what the actual problem is, I dont believe that a customer should have to make a special part to make our product work.

Setting the spring up @ 1.800" minimum will give you the results that you are looking for as far as performance and longevity.

Any doubts please call us directly 1.800.398.6348 or Pete as CNC Cylinder Heads 727.527.8866 which uses a lot of these springs with no failures.

Thanks Ralph

Revtech,
thank you very much for your input. I now feel much better about putting the springs back on my car. You are absolutely correct that the springs that I had were not REV. I don't know what they are either, but I was told by Al at your shop that the outers were not manufactured by REV. I hope you ar nobody else took what I told Austrian as a flame. It was not intended that way at all. I was just answering a PM from him with the information given to me. I am a bit curious that Al told me that above .550 lift was pushing our luck with not only REV springs, but any 1.25 spring and you seem confident that they are good to .610. One other little piece of information that has come to light is that the outer springs on my car were not shot peened and the trend of the broken springs is in the non-shotpeened springs. I hope this helps clear up the info and let you know that I am thrilled with REV's customer service as well as A&A corvettes'.

Thanks,
Don

Thanks for the added info Revtech.

I was beginning to sweat over the previous couple posts since I just had a set of 1116's installed on my LS6 heads. The machine shop I used recommends your set up and has had no problems as of yet. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

West Coast Cylinder heads makes the retainers and spring seats for A&A. It is my understanding that they're designed differently to allow the LS1 heads to get up to the 1.8-1.84 installed height without machining, instead of the 1.7ish that seems to be pretty common. Every time I've seen a cylinder head shop (Norris, etc), they specifically state that they cut the pockets to allow them to get to the proper installed height.

West Coast's website is www.proheads.com and in the following thread, headbam is the owner of the company. It's an older thread, but with lots of good conversation about these springs.

I just wanted to chime in here about some broken outer springs that are occuring. Several sets of springs have been returned to us with a broken outer spring (including 2 on my own car) <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> I have sent them back for analysis and am waiting for the results. I'm not a metalurgist so I won't get into any specifics at this time about the spring failures. When I'm notified, I'll share the news.
As XAON noted, we've engineered our spring kit to yield a 1.830"/1.840" installed height (stock valve tip height of 2.00") which allows for a .610"+ lift cam yet still give comfortable clearance to coil bind. I've not been informed by the manufacturer of the springs that this is incorrect. Of course like any spring setup, our priorities are seat pressure/open pressure then coil bind clearance. To my knowledge there are no known installation specific instructions by the manufacturer, therefore we choose our own. We belive in allowing a comfortable (.060") clearance to coilbind and given that, the 1116 spring will handle .620" before absolute coilbind.
Malibu Vette you have my shared sympathy in dealing with a broken spring. I none the less still believe that the 1116 dual spring is the most appropriate choice for the aggresssive lift cams now offered by cam grinders and I will continue to sell them and use them in my own car.
Indications are that advancements in spring manufacturing technology will bring a VERY, VERY durable spring by summertime. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

You say that hight can be achieved with the REV parts and without any modification?!?!?
