Biggest Valve on 4.030" Bore
Guys, what is the biggest valve that you can fit on a 4.030" bore with ls1/ls6/AFR/All Pro heads? This is assuming stock valve centerlines (I want to use my current shaft rockers).

Thanks guys. Brent, I'm assuming you guys stick with the 2.08's because of the shrouding. Can you get enough air through a 2.08 opening to feed a 408 at around 8000rpm?

Not saying I need them that big but maybe the bigger ports (260cc ish-280cc ish) would be beneficial to a max effor n/a effort with a big solid roller.
