Best 15 degree head on the market??
Hey guys, I am looking for the best 15 degree head on the market for my 423 ci motor. I am wanting to run a 275 drag radial class and they have limited the LSX cars to stock valve angle. So that makes my 235 TFS heads illegal. Im thinking about a set of AFR's but what do you guys think? Thanks

AFR, Dart, All pro
I'd like to see some numbers from AFR 245 heads, promising.
If you source Dart CNC'd heads hey run a 250cc program on them.
TEA CNC's Dart heads, they were in FSC magazine last month.
are you limited to cathedral port?

The big runner LS3 heads PI has might be a great choice if you are limited to a long runner intake manifold. Amazingly quiet at high lift.
