I'm wondering about push-rods for a hemi build. I'll be using a Dynocams CM grind super-x with 22# springs, Arc rod, flywheel, stock rocker arms, carb, header, etc. My question is about push-rod length. I took about 0.030" off of the head to raise the compression & did some mild porting, so the push-rod length is now about 0.030" too long. My fly cutter did an ok job, but I had to grind & lap the head to make sure it was flat. Is this ok with stock length push rods, or should I get the trim to length ones & cut them accordingly?
Next question is the clearance at the piston to head. The piston is 0.015" below the deck with a standard length rod, can I get away with a .010" head gasket, or will I need a thicker one if my target RPM is about 6500-7000?
Thanks in advance, this is the second engine build I've done & a bit different than the first one.
