Which springs are going to be the most reliable & work without machining heads? I'm putting in a comp 222/222 .563/.563 114 and want to get the most worry-free springs that money can buy. I know it's not a big cam, but overkill on the springs is ok to avoid future issues. I have some comp 941 time bombs in there right now with my 215 cam.

I would vote for the humongous MTI custom dual spring setup.

It's the sheez-nitts. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Raughammer,

Is that dual setup from MTI made for the stock spring seat? Or does it require machining of the heads? If it does, how does it compare to the Comp 987 dual spring setup?

My vote is the 987's. When is the last time you heard of a 987 breaking? Never that I know of...

I broke the outside spring on a 987 when I bounced of the limiter once.

I think the 985's may be ok at a 1.8 installed height.

I'd use 918's and use the stock retainers. It's rare people break those nowadays unless they are running a huge cam and alot of duration. I believe the 918's should be great. And there inexpensive.

I like the REV-1116 dual valve springs with the West Coast Cylinder Heads titanium retainers and seat bases. No machining required at all.

If the rev springs weren't available, I'd go with either the Manley springs that MTI uses, or the Comp 918's.

Other than that bad batch of 918s about a year or so ago, I really haven't heard of any 918s breaking when used with cams below maybe .580" lift.

They just drop-in, and with the stock steel GM retainers, seem to work very well. TEA installed them in my 5.3L heads at an installed height of 1.77" which yielded a seat pressure of 140LBs.

So far, they survived the long road trip from Phoenix, AZ to Alabama with no problems.

I'm hoping that if they haven't broke yet, they probably won't break anytime in the near future.

My cam is a TR220 with .553" lift

Another vote for REV 1116's.

I'm running the same cam as you, 222/222 .560 114, youre gonna love it.

If you insist on not machining the spring pockets and keeping them stock diameter, I'd run the Isky Gold Stripe 295D. It's a single spring and made of the best tool room quality spring steel. So I've been told, the majority of Nascar WC engine builders are using Isky's these days. They have proven to have retained well over 90% of their original tensile strength and spring presure time and again after many 500 mile races. Granted WC engines don't employ a single spring but the 295's are manufactured from the same material. If you have the heads off why not machine the heads for oversized springs? It's not that expensive to have them machined and well worth the $$. Plus it will provide you with a far greater selection of spring combinations for you to select from. Hope this helps.

I know everyone wants to squeeze their mod dollar as far as possible, but skimping in the spring area for a cam change seems ludicrous.

Overkill it and have peace of mind, even if it costs a bit more. I have the mti dual setup and spring failure rarely crosses my mind. I've got enough to worry about with driveline parts failing <img border="0" alt="[cry]" title="" src="graemlins/gr_cry.gif" />
