Your deck height is way low. Muir says no less than .040", a "high
performance" engine will have deck height of no less than .060", and some
guys are building engines with .250 deck height. I'd set it at no less than
.125" to get the compression ratio down. (I'm putting .200" on the T4 I'm
building.)
