I was thinking about the pinch on the heart shape. Apparently, it's not a hot spot on the heads. I'll have to look at some blending pics online of a 302 head to see what people have done.
After looking at what I have to do, I think I'm going to pull this engine inspect it to see if I can get it honed. The 318's that I have access to are quite possibly as used, only not as fresh as this one and all of them need some kind of disassembly. I'm just going to ridge ream the cylinders and prep this block as per it's need.
If it needs bored, I'll look for a better block. The .020".010" crank that I have was turned and polished at Colorado Crankshaft. The chamfering looks good on the oil holes and the polish is nice. Inspected with a caliper and it specs out as per their numbers that they stamped on the front counterbalance weight.
Once I get it mic'd, I'll see if I end up honing it myself and burnishing the lifter bores.
