I am thinking about headers for my 64 and I was wondering what headers have worked well for you guys.

I run a set of Flo-Tech cheapies, 1 7/8 ". They bolted right in, and have only one good bash in them from bottoming out.

My hooker super comps had horrible ground clearance. Because my car is low I went with midlengths.

I use flow-techs, I have no issues with them, love them.

I have some used Hedmans in mine...

I'm using stans 2" primarys. They fit like a glove, don't even have to lift the motor to put them in and out

Not sure which ones to use on the 64-67's but the hooker 2455's on my 68 and later chevelle's have worked sweet and the 2457's on my nova/camaro's. Not sure of the part number on the huge super comps on the 69 nova now but they fit great too. Just lucky I guess.

My 70 has no problems with the generic Hookers. Ground clearance is good and the steering shaft is missing a thin layer of paint but I have 2" primaries.
