header question

[white90burb]

I found a set of headman headers on craigs list and I'm not sure if they will fit my 1990 suburban 4x4 350.

"These headman headers are in good condition, they are for a chevy 350 4bolt smallblock. the port size is either 3.73 or 3.23 i dont remember for sure."

If they aren't the right ones you could always resell them. Unless they Re made for trucks, the car ones hang further down and back and you may have some clearance issues. Made sure you bring a straight edge like a alum level or framing square, to make sure the flanges are straight or you will never get them to completely seal and will allways have that annoying exhaust tick.

Sorry about the spelling, have to do this from my iPhone, kids doing homework on my laptop.

ok well I found a better deal. found a set for a 1990 2wd burb. will those work on a 4x4

 

[Phewson1]

Should, the exhaust is the same I think.

so with those headers what type of y pipe would i need to make it work?

i know my hedman tork steps hit my shackles pretty bad. Ive tried to jam a 2x4 between the shackles and the collector and run the engine for awhile to keep the headers hot. Hoping they would bend out of the way, and clear the shackles. but it was a no go lol.
