engine math! milling heads + intake

it's funny you should mention the 167s, i am actually starting to think those are the way to go. i suppose you guys have seen the 400-horse street 318 they built in popular hot rodding, and that build is actually what i have decided to do! they used 360 heads, did not specify how much they took off, but it sounds like .030 will be enough to get my compression up. they said the heads were milled from 72cc to 60cc... i do not know how to calculate how much they took off in thousandths of an inch though. it sounds smarter to mill the intake SIDE of the heads instead of the intake itself, so i can easily change intakes if i decide and still be able to put them back on the shelf and use them for a different application. they also opened up the intakes to 2.02, and did a minor porting job. the block was bored .040 over, and that is what i intend to do with mine. i'm picking up a 318 for free, and have decided that i am going to put the stock heads back on the car for now, run the factory two-barrel, and switch out to the 400 horse engine once it's done and i have gathered everything i need to put it in. this way i can keep the car running and driving, and still be building something that will peg the fun needle. thanks for your advice guys. i think this project will be fun and unique, and really change everyone around here's opinion about my "underpowered muscle car."
a lot of the engine work i will be able to do myself, as i have a full engine rebuilding shop at my fingertips right now. just have to find time to go in and do it!
