305tbi exhaust/headers ideas?
 

1992 1500 305tbi

I'm looking around the used market for some headers, been doing research on high vacuum vs backpressure etc etc... and might bore out the exhaust valve ports a bit if I can get away with it...

but keeping the vacuum and b/pressure in mind, what are some good headers/sizes for my engine to look out for? for both the exhaust pipes coming out the block and the collector pipe?

idk much/can't find much info on sizes I should be looking into

Again it's an issue of what do you expect from the headers. If you go cheap you'll get cheap but I don't think you need to go as far as a set of Thorleys. Both Summit and Jegs sell headers for the 305.

Long tubes with 1 1/2" should be good for a 305. My 5.3 runs good with the 1 3/4" long tubes.
