Question, are 1.85 Comp roller rockers worth any increase in HP?

Sorry, stock heads..

On my 383 with ported stock heads i saw a 25bhp increase at peak, but where they really scored was when the old ones tailed off and the 1.85's kept climbing....60bhp then! If you want a cam later you can get a custom grind to take into account the bigger lift, as i have done. Doddle to fit too. Cheers.

I did the crane 1.8 rockers with the quick lift technology and got 13hp and 21 torque in my mid range over stock
