Yes, I realize I can get a good running take out 12V and make 400 HP. Yes, I realize that electronic tuning can trump simple old mechanical pumps. But I don't think that's what I asked.

I am going to do as I think I have done a decent job outlining. I could use advise on compression ratio as well as 24V vs 12V head from an efficiency standpoint and how the outlined compression ratios would work with each head. That, and a recommendation on camshafts would be great as well.

I'm sorry that I was not clear in my previous posts.

24v head for better flow with a 24v piston I’d say 18:1 is as high as I would go or ring land damage will occur set timing around 21 22ish for decent manners and good fuel economy with a Hamilton towing cam 182 208 would be all you need.
