Magnum RHS Heads horsepower gain??

From LXGuy's thread:

If I had it to do over again, I'd go with less lift on the cam. Its got (EDIT .544, and that's just too much. It causes valvetrain issues, puts a hurting on the springs, and I cant get the cool Hughes shaft rockers because they're 1.65 ratio. I bet if I had .525 lift the power would be exactly the same.

I would also have the heads machined for better springs than the ones Hughes provides (though to be fair I didn't realize they had to be machined for that when I bought them).


The cam is a custom grind hydraulic roller. Heads are as-cast from EQ or wherever Hughes gets them. No porting, no milling. I've got to say, I've been pretty impressed by them-especially for the price.

Cam is 224/230 @ .050. The stall is right around 3800. I've only been launching at 2400.
