Talked to the builder this morning. Block is going to need .015, so we're gonna go right to .030. Crank will need .010 on the mains.
He's on board with that cam i posted yesterday. Still researching pistons, but it sounds like he's found a set thatll get us ~9.6:1 compression, which should be pretty sweet.
Unfortunately, both F4 heads are cracked! One of my E7 heads is cracked at an exhaust flange as well, so its looking like new heads are going to happen.
