408 build

The edelbrock Magnum heads are nice especially when ported. Either head will make great power after porting. The LA head has a slight advantage, but if your not looking for every ounce of power the Magnum version is nice.
I would use the LA heads and Hughes rockers. Best quality for power. You can get a 1.6 ratio from hughes and only 1.5 from comp.
Actually with our RHS head, you can get 450HP easy and not have to spend the extra $$ on the eddy heads and porting.

A nice little build we do will make 440Hp roughly, using comp 275HL cam and RHS heads/hughes 1.6 rockers and rpm intake.
