Just wondering if anyone is running the world products roush 200 heads. What do you think of them. I've got a set and don't know if I should put them on or not. I've got gt40's on my stang now.

Fairly decent head. I have read about some decent flow rates on them . some valve giude work and porting will increase flow by about 5% to 10%. I would give thumper a call, he has some good history working these heads he can give you some insight and he would be the one I would have work the heads. you may be suprised.

No problem. He is a pretty good guy, he posts some good info on other sites but does a great porting job. People are really shy away from iron heads which is fine, but in my area there are a couple of iron headed animals. Heck I run them.
