i have a 90 f250 with a 351w 2wd. my question is will any 351w shorty headers work on this truck or do i have to get specific i can find several used sets local for under 100 but want to make sure i know what i am looking at first

 

You need headers for our generation of truck. Summit sells house brand truck shorty headers for about $150. They are actually Pacesetter brand. Alot of people like them.

 

Yes you need truck specific headers, mustang headers will boltup to the motor(the 5.0 uses the same heads) but wil not mate with the truck Y pipe.

 

^^^^ I have these headers on my 95 351w and i love them.

 

Same here. Bolted right up. I did use gibbson exhaust gaskets instead of the supplied gaskets. Just torque the new bolts to what pacesetter recomends, and you're good to go

 

The summit (Pacesetters) are very good quality, I also have them.

 

what model number are those headers?

 

I think these
