Headers for AFR 185s

[15austin]

I have afr 185s on my 306. I have equal length shorys 1 5/8 on now. The thing is the exhaust ports on my AFRs are bigger than the headers. Im looking at the BBK long tube 1 3/4 in Jegs and wondering if it will give my slower times being too big. Are my current headers fine with good back pressure or should I go with the bigger long tubes? What are some headers others are running on AFR 185s? Thanks

Go with some 13/4 x 3.0 long tubes and call it a day, I've got em on my 302 and it felt better everywhere than my 15/8 shortys

I don't think you'll have an issue with either header provided they're long tube. a 1 5/8" header will suport far more horsepower than you're making, so don't feel pressued to go with the 1 3/4" if you don't feel they fit your needs.

I have 1 5/8" long tube headers on my 331 and am sure they're work just fine.

I think the fact that they were long tubes have more to do with how much better they feel, than their diameter.

My buddy had a car with 1 5/8 equal length that went well in the 10's. Spend your hard earned dollars elsewhere if you ask me.
