sb alum heads edel vs indy

You can build a 408, rhs heads and a good sized solid cam and make 520ish hp.

Mad_Dart built one using Brian's heads and that engine would easily be capable of powering a 3000-3200# car to 10.60's in a good chassis.

If you are wanting to run ~10.00, then ask DusterDoug about the engine in his Duster.

Would running 10.00 be easier using a fully ported ede or an Indy -1 head, likely, they also cost a bunch more.
