Got another one. A 416 this time.

This may be one of four potential places for the heat shields to cut into the manifold, I grind the shields back a bit for clearance.

I will make sure there is clearance for all the heat shields during assembly.

When I clean a carb I like to remove the plug circled in blue and remove the main jet for cleaning.   On one of my carbs,  removing the main jet allowed me to flush some additional debris out of the passage the main jet screws into.  On an engine that already runs lean from the factory, this can be critical.

There was real good flow out of the main jet when back flushing with carb cleaner so I think it will be fine.

I can remove this on the engine if necessary later on.

Intake has been split, cleaned, tapped and bolted back together with a thin coat of sealer.

Intake was then pressure tested to 5 PSI and checked for leaks, none found.

I did that last summer and unfortunately I did not get pictures.

What sealer did you use?  I resealed a manifold 2 years ago using Motoseal 1 based on the recommendation of another Redsquare member.   Came out well.

I used Dow 732 sealant mainly because that is what I had on hand.

Intake assembly ready to be installed.

Bolt length is 2" for maximum thread engagement without bottoming out.

 

Intake manifold to block gaskets used.

 

Engine ready for intake installation.

Threaded holes chased with bottoming tap for maximum thread engagement to help prevent stripping.

 

Intake gaskets sat in place.

 

Intake assembly sat in place and loosely bolted to rear cylinder.

 

Dipstick tube bracket installed and front cylinder bolts installed.

Intake bolts torqued to 96 in/lb.

 

Dipstick tube screw installed and tightened.

 

Intake manifold assembly installed.

Wire harness is still able to be moved under the manifold so it is not pinched.
