Well I discovered a little more about the Crate engine I picked up. Tore the heads off it this morning. It is .060 over with typical stock dish pistons. Motor has two different casting heads on it. Same chamber and valve size just different castings. One head has decent valve seat hieght while the other should have had new seats put in. Definitely isn't the new GM crate engine I thought it was but more like an Advanced auto special....... Bright side is I have a fresh bore and flat block to work with.
Been looking at these heads

Over the top of a decent flat top piston, headers with a decent intake and 600cfm carb. Now to hunt the rest of the parts down. Local swap meet coming up in November.
