You can also use the good GM .028" head gasket and deck the block a bit less too. This allows for future rebuilds, future block decking. With the .028" compressed GM head gasket you would want the assembled piston deck clearance to be .012" .015" @TDC. Getting the assembled piston to head clearance (quench) .040" is all part of the success of this build.

The cr ends up the same as a 0deck and .041" gasket .. Set the piston ring end gaps a bit bigger than typical-- normal, for this boosted high power engine.

The rings expand more when under the high heat load, under high boost WOT.

Try a corvette forum and searching for a diy. There should be a writeup on it somewhere.

One thing restoring a old car that hasn't moved in ten +years has taught me is a acceptance for RAT **** and a higher tolerance for SPIDERS!!!

You might benefit from a MSD Boost retard. If this is driven on the street and requires a curve to react to different driving. Made all the difference in my truck after I gave in to the purchase. You can go max timing and have no detonation. My detonation began at around 4-5000rpm. Making only 5 psi boost. No matter how the mixture was enriched or timming reduced it did not solve the problem completely. The BTM solved the problem my engine was experiencing, and allows maximum power extraction in the package.

ive replaced the starter already all 15lbs of it , car still wont start i have a optima red top in it brand new now the only thing i can think of is its the battery cables they dont look super hard to replace but ive thought that about a lot of things on a car and been wrong , the positive has been replaced before so it leads me to think that its had this problem before

Run the battery + circuit in parallel. make the two red positives from bat to starter the same gauge and conect from the same places. Voltage will stay the same amps will double. It is ohms law.

Check the ground.

Cable are bad. I had the same problem. Replaced starter and battery and nothing. Turned out to be a stupid $10 cable.
