Default Iron Vs. Aluminum ?

OK guy's here's the deal...I currently have a set of World Windsor Jr. Iron heads supported with Scorpion 1.6 RR...I keep hearing AFR & TW aluminum heads? I know the current heads I have are good however, am I getting the real HP I need? The specs on the Jr's are Solid/Hyd.Roller Iron Head 180cc 1.94"x1.600" 11/32 1.437"Dual 125# Seat .600" 58cc

I know heads make a Hugh difference. Can you make a good recommendation?

stroke the motor, new heads later(AFR 185 etc).


I believe on a dyno the AFR will do about 40hp above what you have, aint worth the labor for 40 ponies to me.
