Default SBC head flow chart?

whats the highest aftermarket head flow? I read about the AFR's and they are amazing but is there any heads that flow over 300cfm like AFR LS1's ?

I don't really care about SBC stuff, but there is some heads that are over 400 cfm.

No idea who or what they are made for??

Ok, I just checked Brodix, they have a SBC head that flows 430 cfm. See if they make your application??

Flow isn't everything though, make sure you go with the right runner cc for your cid and rpm.

I haven't ran it since I loosened the convrter and put super comps on it. I was mph 127 with a 1.60 60'. THese heads would pull to 8000rpm if i let it.

The dart and brodix cnc 227 heads flow in the lower 300 range around 301-309 on the bench that I use.

That is what the new AFR 195cc are flowing. And for a street build sub 400cid, that is what you should be using.

So would some 200cc Iron Eagles match up pretty good with a flat top 355 with a RPM Performer intake and a 750 carb?
