Thanks for the comments, guys!
Those are Icon forged units on 6" Scat rods. I had the domes milled a bit for a target 11.0:1. The machinist used the component specs instead of a four-corner mock up for the deck job and told me they'd be 0.010" in the hole, so I bought 0.030" x 4.060" laminated head gaskets for a 0.040" squish. Well, once we got it all together it comes pretty darned close to a zero deck! The heads are 461s that I had cut for 2.02x1.60 valves. I had chambers cut to unshroud the intake and used 8mm valves. Chambers came out to 65cc. All the runners are gasket ported and worked a little bit. Actual CR is looking closer to 11.2:1. I'm going to run with that and will punt if detonation is an issue. A 0.040" x 4.100" gasket will knock a few points off it. Knuckles has also been showing me an Engine Masters episode where they compared AFR heads to the Camel Humps. We're hoping to get back on the tools this week.
