Upper Intake Manifold Stuck
Hey guys,
I'm having some real trouble removing the upper intake from my '93 302 EFI. I have removed all 6 bolts, and I still can't get the thing off. Some fool decided to use RTV the last time it was apart, and I now cannot pry the thing off. I have tried using a rubber mallet to loosen things up, a pry bar + 2x4, and I even ran the engine for a while with all of the bolts out to see if the heat would loosen things up.
Does anyone have any other ideas? - I need to get the darn thing off so I can change the injectors.
Thanks!
Jack.

Maybe a torch around the perimeter? How long was the 2x4? I would think with about a 6' long one going in under the upper from the passenger side and prying up it would break loose, maybe you've already done that but I can't imagine RTV being able to when that battle.

There's really limited room for a 2x4. I managed to get the throttle body off of the intake with the torch, baby sledge, and a brass rod. There's not really room to torch the upper intake itself, so I've just been going at it with the sledge and brass rod. Hopefully I don't crack the thing but honestly I don't even care if it gets it off.

I removed it all. I should have mentioned that I was the fool who used RTV, so I was already familiar with the removal process 
. I finally got the thing out after beating the crap out of it. Now, though, one of the damn injectors is stuck. This project has been quite the pita.

As mentioned, the upper/lower gasket should be completely dry.
If the gasket moving during installation is a problem, whack the heads off a couple 5/16 bolts to use for alignment studs.
