Re: Compression and flow
I've been in this area fo the Flathead almost all my life, and there isn't really an answer to your question. Application controls most of it. My experience is in small engines on a 1/3 mile track and drag racing. with no rules, you can do anything you can afford. that's why their are rules./ I prefer to modify the stock head, price wise it offers more. I thinl the Grancore head is probably the best after market one, But if you run a blower , boost wins ask RR. The best thing about racing is!!!! Competition!
