I'm replacing the heads on my 87 2.9L V6 and I need new exhaust manifold bolts; complete set left/right. Anyone know where to get these buggers?

@RANGERICK ,

I always use Stage8 locking header bolts, I have read that several individuals replace the bolts with studs and nuts. I have a great fastener store near me that I would consider buying 12 grade 8's with washers or a set of stainless steel bolts, either way I would expect it to be less than $20 unless you decide on something like the Stage8's which are about $70 a set.

Bolts are metric M8 I believe. Not sure there’s a kit or anything. You’re going to have 6 short and 6 long if I remember right, but I don’t know the exact measurements. Stainless would be nice, but you may have a hard time finding what you need without changing to headers

Gaz, I found a source but I need to confirm sizes before I buy them. This is what I got from Bronco Corral M8 1.25x75 (8), 1.25x50 (3), 1.25x 30 (1) Can anyone here confirm those sizes?

The bolt set is a set of 12 fasteners which are all the same size;
it sounds like you are considering the Stage8 set, I recommend looking up the part number from SummitRacing.com for the engine you are using.

Stage8 part# for Ford 2.9l and OHV 4.0l is 6919.
