champ alums take different push rods than irons (and studs as you know) , and if you have t&d rockers and intended on using them on the gn1 alums with stock shaft style rocker think again , the alum head are spaced different and wont work with stock rockers or stock T&D shaft so youll need new or send them to t&d for redo to gn1 spacing you could forgo the gn1 pedistals cracking issues with the shaft style and and instead get the gn1 jessel style rocker setup similar to chevy and not have to worry,, also whats the bore on your block , alums move the valves further apart so as to accomodate the larger valves and beleive they dont work on std bore and even on +20 the top of bore in block should be releived a little to unshroud the outer edges of the valve

The current Champion head that is available is a very nice piece. Very heavy duty, flows well and I seriously doubt you would have any trouble with it under normal circumstances.

I bought the TA heads for my car after seeing all the horror stories with the Champion heads. I don't think anyone has ever broken or cracked a TA head.

I went from 8.400 to 8.500 when switching from iron to TA aluminum. BTW Nick... your shortblock is still in the car and plugging away. When I switched heads on that motor, I had a hellava time finding valvesprings that worked with that cam you stuck in it. I finally got a set of 26120 beehives on it that seem to work on those pointy lobes.

Now with ported GN1's it will run low nines with less boost. If built right you can run 9s in a street/strip car with GN1s.
