Go here or have your engine builder go here: HeaderDesign.com

Register at the site and use their calculators. You'll get accurate information for your particular engine's characteristics (including things like "Exhaust Port Length in Cylinder Head", "Performance Factor (how will you use this engine)", etc. You won't be sorry (and you'll probably find out that VintageMusclecar was right on the smaller tubes). Then you can find the right header manufacturer for you based on price, fit, etc.

The big tubes always look tougher but aren't necessarily the right performance answer.

Thanks again guys...Yeah, when I talked to him last night he was saying he's been thinking of keeping it small...So 1 3/4" seems to be a pretty common recommendation.

Since he's having this mechanic in town do the job for him, he's wanting to work with him as much as possible. (Don't want to piss a good mechanic off..especially in a small town).

Dad likes Hooker Headers but since the mechanic has had problems installing them, dad's looking at other brands. Since all headers rust eventually he's not looking to spend a ton of money on them.

I have run FloTec headers. They fit perfect, yes even better than Hooker. You can get them already coated and they hold up fine. A set of coated Flo-Tecs will be about a 100 bucks cheeper than uncoated hookers. m

Thanks again guys...I guess he's found a header shop up in Eugene Oregon and headers and performance exhaust is all that they do. I think he's going to take it up there and let them fool with it. I guess they've got like 200 different styles of headers.

Dad started having second thoughts about having someone work on his car that has a tendency of blowing their tops! Can't say I don't blame him. He also found out today that the ones that are on there are Hedman Headers...Not sure about the tube size though.

He's leaning toward the FloTec's...
