You must be the "talk about it" type.
I do it... and I do it looking bone stock.
If you dont get it, if not interested... then move to another thread about aluminum heads.
No, I'm the go fast type and dont care that my engine doesn't look stock. This engine is going to have a .575 lift cam, Victor intake, a Holley carb and most likely headers so it's not going to fool anyone into thinking it's stock. I could understand if it was a FAST type build.
My advice to the OP is to call some good head guys and pick their brains, they'll give him the pros and cons of both types heads.
Is this a street or race deal? If it's a street deal with iron heads and 11.0-1 what gas is the OP planning on running?
