Default Hedman Header peeps step inside please

'90 auto

Brodix Track 1 heads

Now I've heard of fitment issues with the ports not lining up on some of the Corvette heads. Well I am wondering if I will have any issues with bolting these headers to my heads. Hedman part # 68440. Yes I know these are the cheap ones, but I've pretty much run out of money for this car and still have a few more things to buy like tires .

Interesting... I had not heard of fitment issues with Hedman's. In fact if you go through the archives, most owners say they fit very well.

Of course that was for stock heads. I have no idea what changing heads will do to fitment issues.

*wonders if this thread will get ugly

I hope not, thats why I put in my original post I realize they aren't the best in the world as far as headers go, I'm not asking that question, just can't spend the money right now for hookers, maybe next year.
Just need to know if they will fit right.

The fitment issues are how they line up to the ports. All C4s from mid '86 on have D port heads. If your Brodix heads are D port, you don't want these.

The 128 heads that came out in 1986 have square ports. The "D" ports weren't introduced until the 113 heads came out. I was under the impression that the port fittment wasn't a problem, except with the LTx heads. It looks like I may be wrong about that. I would check with both Hedman and Brodix. Those headers are the size you want and apparently the price you want.

RACE ON!!!
