Re: REV-1116 Springs These are supposed to be installed with new vavle seals, too. Here's the info on these springs:
INSTALLATION:
Before beginning the installation, be sure to obtain new valve seals. We recommend GM parts #'s 12533586 for intake and 12457652 for exhaust. These seals will replace the late style one-piece seals. The spring kit #WCSK1116 was designed to be installed on any LS1 or LS6 providing the valve tip location is at the factory height of 2.000". If the tip heights are greater than the factory measurement, it will be necessary to add shims under the spring locator. The spring pressures and heights are listed below. Typically, spring seat shims are available in .015", .030", and .060" thickness. Installing the spring assembly at the factory tip height (2.000") will result in an installed height of 1.830" - 1.840" as measured with the spring locator; this results in spring seat pressures of 130 lbs. It is important to be sure to remove the original OEM spring base before installing the new locator! Care should be taken in removing and reinstalling the valve seal.
Rated spring pressures:
Installed height measured with spring base:
1.840" 130 lbs
1.290" (.550 lift) 355 lbs
1.265" (.575 lift) 368 lbs
1.240" (.600 lift) 380 lbs
1.220" (.620 lift) 387 lbs
1.160" (.680 lift) coil/spring bind

Re: REV-1116 Springs What's the proper method for installing the valve stem seals? My stock ones (built into the seats) where pretty self-explanatory, but the new ones just seemed to rest on top of the valve guides (and stuck there one they were sitting on top of it). Is that all that was supposed to be done, or did I miss something?
Reason I ask is because i'm getting a little bit of oil burning on startup like my old 79 model car did (valve stem seals were toast in it).

If I have those, I have to switch over to the valve seals listed in his instruction sheet. If not, I'm fine.

Re: REV-1116 Springs The new seals should push onto the valve guides with moderate pressure. A few drops of oil will help this. If your fingers get wore out, try using a twelve point 3/8" deep socket to push on the outside of the seal body. Do not push on the seal lip or spring! Once the seals are seated firmly in place, they will stay attached to the valve guide.

Re: REV-1116 Springs I have had these springs for just about a year now.. Mike and Norris Motorsports did a great job and I haven't had any problems what-so-ever. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: REV-1116 Springs headbam: Cool, that's what I did, i pushed them down againt the valve guide and then tried to pull up on them with my fingers, they all stayed stuck to the guide tightly.
Joe99SS: Glad to hear that! I've got about 600 miles on mine so far, with about 10 passes at the track. (along with dozens of 50-110 runs on the street). They seem to be holding up great.

Re: REV-1116 Springs Yeah. I found that out after I got my springs pulled off and sent that information over to andy. I'm just wondering if there's a special "install procedure" for putting the old style (two peice design) on. They seem to have just wanted to slip over the valve stem and sit on top of the valve guide (they appeared to grab hold of the valve guide and not want to pull back up very easy), but I'm not sure if this is the complete installation procedure.

Re: REV-1116 Springs Do you guys suggest I pick up the spring seats from Andy or will I be alright with the ones from REV. I have the REV ones already.

Remember the 1116 springs coil bind at 1.160". To be safe, a minimum of .060" above coil bind should used. That leaves a safe solid height of 1.220". An example is listed below:
Installed height = 1.780"
Max safe coil bind = 1.220"
Max valve lift = .560"
If you plan on running a cam with more lift, you'll need to obtain the A&A retainers and seats or machine the spring pads in the heads.
Good luck,
Richard
