i'm pulling the engine, mainly to detail the engine bay, and add long branches, didn't plan on going into the bottom end (10000 or less miles on rebuild)but want to get this right the first time so i'm open to anything. this deck hight issue! i have read that zeroing it out is better, because there is nothing above the piston to heat up and you get a better quench (what ever that is, please tell me) but it also increases compression. can this be over come by dishing the pistons and enlarging the camber on the heads. and is there anything to be gained by porting of the heads +/- 240 cfm. it's a driver, 5000 rpm is about it for me and not that much of it. do any of you know of an early q-jet for an auto.
