DOUBLE SPRINGS: what do you suggest? I'm going to go w/double springs on a stage 2 head with say a 224 114 lsa cam. Are there any differences between brands when it comes to double springs? Any brands suggested? Or, are all double springs the same?
Thanks guys!
Thanks guys!

Re: DOUBLE SPRINGS: what do you suggest? The REV-1116's.Thet are 1.25 and you dont need machine work for them to fit your heads.They should be plenty for that size cam.If you want bigger then I would go with the cranes they are 1.46 but need machining to fit.

It was like 160 pounds or so. I have a friend who engineered the LS1 for Gm and he said that should not cause any trouble? 135 is pretty wimpy when you think about it. Stock is 130. Sure the valvetrain is gonna get some pressure but I dont think enough to worry about

Re: DOUBLE SPRINGS: what do you suggest? Well, with a cam that is going to have a .563 lift - will getting double springs be a good idea? I thought that going with doubles, they would be less likely to break?

Re: DOUBLE SPRINGS: what do you suggest? Stock seat presure is NOT 130!!Your friend is a MORON if he thinks you should run 160SPSI w/a hyd roller..
Guys DONT do this,Your gonna be sorry.
This spring should be setup at 1.84@135...
Make sure u contact West Coast Cyl. Head/Andy at A&A Corvette for the CORRECT retainer for these springs.

Re: DOUBLE SPRINGS: what do you suggest? yea, it is no where near 130 stock.
you are lucky to have 70 psi on the seat stock.
the highest i have seen is 68.

Re: DOUBLE SPRINGS: what do you suggest? Do the spring seats from Thunder Racing give you the correct spring height as well? Or is A&A Corvette really the only place to get them?

Re: DOUBLE SPRINGS: what do you suggest? Dont know,I would call TR..
But if u want the best way to do it,Contact Andy@A&A Corvette or WestCoast Cyl. Head.
The guys are West Coast had these custom retainers made just for this application becasue the REV parts setup w/TOO much seat pressure and could cause coil bind,lifter wear,valvefloat or spring failure etc....
Here ya go....

The 987's have about 130 seat pressure and 330 to 340 open if memory serves.
REV-1116 might work out very nice since you can skip machining the heads.
