You could buy some ghetto ass ones off Craigslist like me and cause yourself a three month headache!

Is it a safe estimate that upgrading the heads will give 20WHP?

It probably depends more on which heads you get. Which did you have in mind?

Please see 1st post of this thread. Just looking for general expectations. wondering if 20WHP gain is a good expectation from those who have installed upgraded heads.

I would say minimum 20HP. Air flow is everything when it comes to power production. Of course everything depends on whether the head porter knows what he is doing.

I picked up between 80 and 100 HP when I replaced my iron heads with ported aluminum heads. Went from low 13's to low 12's at the track.

Maybe ask that Chris guy if he has any dyno charts. How much is he asking for a set?
