If this is going to be a budget street build you have an option to work with the heads you have. Do some porting on your iron heads and port match the intake.
A good valve job and down the road you go.
The old heads are lead heads I believe, I want the wait reduction too. They aren't worth dumping any money into so I wanted something more modern with the benefits of aluminum. It is a little more than a budget build too, but not radical. That is what the roadrunner is for. This is going to be a nicely powered street machine.
