I am contemplating opening up the chambers some more on my heads. At the same time I will have the heads O Ringed. I need to know which gaskets to buy. But first I need to know how thick they can be without screwing up the quench area. My pistons come OUT OF THE HOLE .014. Result of 6.125" Rods, 3.905" Forged Pistons, and a .004" clean up on the block.

So what is the optimal quench...is it a .054" thick gasket like the stock 2002 MLS gaskets or can it be thicker? Since my pistons come out of the hole .008" more than stock (.006) does that imply that I can go to thicker head gasket...what should the quench area be and how thick should/can the head gasket be without screwing up the quench area???
Thanks

You could add a head gasket that is .008 thicker and maintain the stock static quench. You just subtract the distance out of the hole from the compressed gasket thickness.

It sounds like the stock static quench is .048. I'm no expert by any means on this, but I have read that you loose all the benifit if you go over .060.

A HotRod magazine article I read called for .037 - .044 as optimal with steel connecting rods.

I would try to stay as close to (or below) the stock quench as possible, since it provides a free octane of sorts.

i would shoot for .035 to .045...

i wouldnt go much thicker than the .054 you mentioned, that would give you .040.

if they make it for an ls1 maybe get a .049, that would give you .035 which would be the minimum i would go.

Also remember you have to use graphite or copper head gaskets if you oring the heads. You can't use the MLS style gaskets anymore (if oring is in place).
