Who can tell me?

[Never Satisfied]

I am scrapping the junk headers on my 86 and have a real nice set of original manifolds to go back on. I was hoping someone could tell me what length bolts I'll need for these manifolds? The flanges are 1.5" thick. How far do the bolts sink into the head?

I don't know the depth, but I would buy two sets. One 1/2" longer and a set 3/4" longer. Then you could take the extra set back you don't use.

the bolts are 3/8" by 2-1/4" from the factory. I use 2-1/2" with lockwashers and so far so good

Yeah, I guess that's probably what I should do, just to be safe.

Awesome thanks!
