OEM Exhaust Manifold Tight On Studs

[fikemoo]

Hi guys, due to a change of plans with my build I've reverted back to the factory exhaust manifold. Trying to fit it up today it seemed to really struggle getting over the exhaust studs, I have changed them so they are all brand new studs but I don't imagine that would be the issue. I'm sure it wasn't that tight to remove (although it was taken off a while ago) any advice would be greatly appreciated.

Is this an rb25 (single manifold)? On Rb26 I've had this issue where each factory 3 cylinder manifold has shrunk a little with the heat cycles and I've needed to grind out the hole for the studs a little....I would not be surprised if you could have the same issue but more so with a 6 cylinder one.

Hi apologies it is a RB25 turbo manifold, i test fitted the new replacement gasket and that fits as you would expect so the issue certainly is with the manifold itself

Had same problem with my rb25 manifold. Looked what studs were fowling and made those manifold holes a bit bigger with a die grinder. Should only take a few minutes to do.

Appreciate the replys guys, sounds fairly common then just wanted to make sure i wasnt missing anything obvious
