Ok, I wanted to ask because I didn't want to "experiment" with these heads and have the car fall on it's face after 3500rpm or something dumb like that. Like I said, this one isn't going to be a racecar. just a driver but, I want it to run well also.

I get the sense that you really, really, want to know about those teener heads. And if you don't try it you will never know, and you will be forever wondering. So with that in mind I'll offer this; I have been able to use the Fell-Pro .039 headgaskets at least 3 times. They are on their 3rd life in my current engine for at least 12 years and pushing 100,000 miles and on 10.7 Scr.I have also, reused the FelPro intake gaskets. And I highly recommend a smallport single plain 4bbl intake,to go with the teener heads. This is not a deal breaker, but once you try it, you'll know why.
So I'd have to say, don't be afraid to satisfy your curiosity. It will cost you a few hours of your life, and a few dollars in sealers and glues. Then you will know.At the absolute worst you will have a story to tell.I love to tell my story.
Oh, and that teener top end still likes headers, and 3 inch duals! Let it breath,let it rev.Have fun.
