Hi,

Can anyone tell me the thread size for bolting the exhaust manifold to a Crossflow head? My donor had a few bolts missing.

Thanks,
Simon

IIRC the head is tapped 5/16"UNC the studs are threaded 5/6"UNF on the outer end and normally use brass nuts. Burtonpower stock the studs and nuts.

Hi Simon. Yep the above is correct. Now if i had known i could have put a set in with the other bolts.

Thanks to you both.

Matt, if I had known I would've mentioned it! I always discover I need something else right after somebody has sent me something or I've ordered it.
