The exaust is bolted to the intake just like it was when I removed it. I didn't separate the two pieces for fear of breaking the bolts. I didn't have the manifold surfaced, I'm hoping it will sit fairly square against the head without machine work.
I don't see how to reach the bolts with a torque wrench. I was planning to use a normal wrench and tighten by feel. 15 to 20 ft-lbs for the inner bolts and 25-30 ft-lbs for the inner bolts. Gaskets go on dry with the silver side towards the manifold.
Is there anything I should be aware of before getting started? | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | If you haven't already I would chase any bolt threads. Anti-sieze can help ease removal if necessary later. After installation if idle is rough, maybe there's a vacuum leak if surfaces don't mate tightly. Don't forget the intake alignment sleeves(rings). It's a simple bolt on. I wouldn't worry about torquing the bolts. Snug them up tight.

But I did clean the threads with penetrant and compressed air. The bolts cleaned up nice on a wire wheel and I applied anti-sieze. The gasket was very difficult to install, it was tight around the alignment sleeves. I just jammed it on anyhow, probably deforming the gasket a bit. Hopefully it seals. My gasket kit is for a 216 but the head is a 235. The bolts I did up even and snug, but not over-tight. They can be tightened more later if they leak.

The crowsfoot adapters should be fairly easy to find, any parts store or Sears should have them. The box adapters might be a little trickier to find, I got mine from Snap-On.
for chasing threads, you'll want a thread chaser tap and die set, rather than a dull normal tap and die. The chasers are made to clean and reshape the threads, rather than cut new ones. A dull regular tap or die may actually cause more damage. A good set of chasers, with standard 1/4 though 9/16 in NF and NC, plus metric from 6mm to 14 mm can be found for around $50 US at Sears, Snap-On, and most other places. They are a very good investment, especially if you're going to be doing your own service on vehicles.
