Well sir, thanks for your help. That's why I threw this up in case he was wrong or I was mistaken. You think a mill-job would make ANY difference in the seat-of-the-pants feel? If not, that's right at $100 I can save. Thanks a lot for catching that grey matter.

I hope so buddy. I've been on HPJ for about 3 years and haven't made it out yet. I plan on it this year. I'm also going to Mustang week for a couple of nights. You heading out to dragging rights BigBlock? Also, are you on HPJ?

Slight change of plans; the heads are fine and my buddy is buying them today. I have a set of stock 317's that I'm thinking about milling. Anyone else making good power on milled but un-ported 317's?
EDIT- I just got off the phone with the my machine shop and he said the difference of the combustion chambers could be evened out by milling the 317's 0.25". IE- a set of 317's milled 0.25" will yield the same CR as a set of stock 243's. I've read that 317's outflow 243's stock-for-stock. Is that true?
