360 heads on a 318

It's always an option. It's not how I would do it, but it's an option. You will also have to mill the intake to fit as well. Then, you will have an intake that will work on only one engine.

Again I appreciate the feedback.

I know its not the best approach but its almost free and a practice at porting for me. The Heads are just sitting doing nothing anyway and Im sure most would consider them junk and scrap anyway. I can pick up an intake fairly cheaply I assume and mill that to match, so thanks for that, its not something I had considered. So I'll need to mill the intake side of the heads and mill the intake itself to match?

If this small project works then when I finally have the 340 built the 318 will be sold with the 360 heads, intake and carb. I'll be going another route with the 340.

Given that you believe these heads CC at 76cc then what do you think I could successfully mill off the heads to get good compression but not ruin the actual heads themselves?
