Right now I have headmen 1 5/8 headers on my car. I going to swap in a new motor with fastburn heads. I have been searching online, but I cannot figure out what headers I will need to use with these heads. They have D-ports. Can I use my current headmen headers or will I need d-port headers and if so who the makes them that will fit in a third gen. The headmen website is worthless.

 

I found the answer to my own question. Hedman does make a D-port shorty header for Third gen camaro's running a Fast Burn or LT1 head.

Yip, same ones I have. I had the coated ones on order but after waiting two months for them I cancelled and got the non coated (68479). I also ordered from summit so be prepared for delivery times set back almost weekly

Original date was a month after ordering, then every week after that it was pushed back another week. Hope you don't get the same as I had if you order the coated.

 

Just FYI:
Dyno Don's 1 3/4 shorties are available with "D" ports as well.
