Ther seems to me a lot of info out there about header size for our modular engines. But I've no real matrix, if you will, that one can pic out the right headers for one's HP/TQ goals in terms of boreXstroke, cams, NA/FI....etc.
Lately a lot of folks seem to think that 1-3/4 headers seem to always beat 1-5/8 headers for anything NA?? over 400+?? HP.
