Reply to "More Info Needed for Aussie Head Swap"

quote:
by the time you've set up a set of iron heads with the good valves, springs, porting etc, you have spent a fair sum of money but still have heads that perform worse than a set of alloy 2V heads from Trick Flow, AFD or CHI out of the box. The alloy heads will tolerate more compression and have slightly larger combustion chambers. You'll be able to run a milder cam with the alloy heads.


This is pecisely why I went with alloy heads. I went with Edelbrock 2V aluminum heads from DSC Motorsports in CA. They've had the bowls and ports cleaned up a bit and larger valves installed. All for only a few hundred more than the cost of R&Ring my cast iron heads.
