360 build ????s

Well for an update.

Some may disagree with my choice but I decided to stick with the 318 that is currently in the car. I know this motor is sound. It does not smoke rattle use oil or anything. Also this direction for the time being is friendly to my current budget and will still make a fun thumper to beat on. I am going to install the purple shaft 284/484 cam, use J heads, Torker II intake and most likely swap to a Holley carb.

My question this time around is. The 318 is a 78 setup. Does anyone know off hand if the pistons pass the block surface from the factory? ( Sorry for the lack of correct wording, positive???) Reason I ask is i dug into my heads some more. They have been milled .100. So obviously need to worry about piston to head/valve clearance. One positive thing is this will help raise my compression if I can still use these heads. I am only asking on here rather than looking for myself because I just found out the info on the heads this evening and do not have time till next week to tear the motor down to see.
