67-72 C10 lsx swap header questions, of course.

[C10LSX]

Hey guys, I know there are tons of posts for different header swaps for c10 ls motor, I'm just trying to find and answer to one.

I've got a 69 c10 with 5.3 and I've looked all over but have really seen any answers about if 4th gen F-body pacesetter headers will fit 67-72 c10 pretty good?
I know they won't perfect but I wouldn't care to grind a little frame or mount or something, just want to know if it's worth it...

I found some used ones pretty cheap and was thinking about trying them, just want to see if anybody has ever tried them or running them. If they don't I'll get some TBSS pacesetters cause I've seen ppl with them.

Any help and pics is greatly appreciated!! Thanks guys!
