i wanted to know if my hedman long tube headers (1 5/8) will fit without problems on afr 190 heads. what heads would i have a problem with trying to get those headers to bolt up to? ive heard of some heads having different sized exhaust ports than the headers, causing problems and stuff. thanks for all the help

 

They will fit on your heads. The mounting holes are the same. I think what some people are reefering to is the port volume. That is unless you have completely changed the exhaust port by a bunch of hogging out,
