I've doing some planning now because soon I want to do my engine build on my 99 Cobra. I have done some reading in the past and cannot decide what would be best for my combination. So here goes:
I want to build my engine to hit at a MINIMUM 400rwhp on stock cubic inches, although a forged bottom end. I have read that FR500 heads are one of the best heads for the DOHC engine, but that people have had success with ported 03/04 Cobra heads and ported Mach 1 heads.
So, FOR THE MONEY, which would be best suited for my application? Would stock FR500 heads outflow a good ported 03/04 Cobra head? Would I be better off buying some FR500 heads and having them ported to make the most power possible?
I just want to make the most power possible N/A obviously, but if it's not worth it to buy the FR500 heads when I can make good power with the 03/04heads then that path would be great too.
Thanks in advance
