First off id like to thank everybody who has helped me out & given me advice on my engine so far. Im still learning my way around.



Ok so ive never bought a set of headers before and doing a quick search on google brings up mostly chevy junk. im not familiar with different companies and so forth. also ive found tons of information on A Body fitment but not so much my body & generation. I need somebody to steer me towards a good company that wont charge an arm or leg but has a quality product. also fitment advice, what too look out for. I would like to go long tube but if fitment is going to require a lot of changes I will settle for shorties. I would imagine that being a bigger car it probably has a wider frame but I don't want to just assume there is extra room.

 

The b body didnt have much changers over the years. I think 1990 was still very similar to 1977 when they went to the shorter wheel base. Im using A body ( cutlass ) headers On my 1977 pontiac bonneville with an olds 350.

 

yep 77 through 90 are the same. what was it like putting them in?

 

The fire wall needed a little massaging and i hammered a pipe. but had i had the engine out i would have trimmed the lip where the fire wall meets the floor pan and i would have probably cut the one tube on the header and welded in a less extreme bend in.

 

cool how was it around the crossmember area?

 

Don't be afraid to modify a set of headers to get them to fit. Here is a good video to watch:
