Something wasn't sitting right with me about the headgasket thing, so late last night it gave me another excuse to re-read Mr. Bell's excellent book, "Maximum Boost". If you don't have it, highly recommend a trip to the bookstore to pick it up. If you do, refer to pg.157 where piston/head squish volume is discussed.

So instead of staying awake thinking about that, I began thinking about a heat shield for the A/C compressor and also design for lower intake temps (knock threshold) without sacrificing too much cfm.
