The iron heads made great power. No need to spend prohibitive money trying to make the aluminum heads work.

What is the catalog number for the Eddy heads. The one listed on nhraracer are big valve heads. Do you have to put smaller seats in the head?

Yes you have to change seats and the make the runner the same size as OE head you're replacing. Next question becomes how to do that legally!

Yes. Get out the wallet. I have a set and the work it takes is not rational. Look at the CC numbers and get to thinking about that for a minute.
