I recently bought a complete 390 engine and finally got around to see what the innards looked like.
This is a C7AE engine with matching heads and 4v intake. The heads have been rebuilt as the ex seats have been upgraded, but the bore is like brand new no ridge and the crosshatch is almost like new!
Mention to say it is a standard bore with original pistons and standard crank.
The guy has had it in his garage for years and said it came out of a 67 wagon that was t-boned and he bought the drive train out of it. Only thing it didn't have was the lifter valley heat shield.
Question is----- does any gasket company sell intake manifold gaskets that have the heat riser ports blocked off, or do I just have to fill them with some kind of metal or tin?.
Thanks, Bud in AZ

I’m certainly not the end all be all on this subject but I’m not aware of any off hand.
I’ve used pieces of stainless in the past.
-
Mr. Gasket 202A for medium riser ports and 206G for low riser ports have the heat risers blocked. Pretty sure you need the 206G gaskets for your application.

Thanks for your response, I will check it out!

Jay what’s the scoop with those gaskets do they use a steel insert that is part of the gasket?
Can’t find an detailed pic.
-
The Mr. Gasket gaskets don't have a steel core. Even though they seem to hold up pretty well on the exhaust crossover, I'd probably go ahead and use a piece of stainless to help block them off. Other gaskets, like most of the Felpros, don't seem to hold up so well to the exhaust gasses and will blow through. That's been my experience anyway.
-
That’s where my question was leading.
-
Doug is right, no steel core in the Mr. Gaskets, they are just a composition gasket. But, for whatever reason they seem to hold up pretty well. However, I'm not sure I'd trust them to stay intact at the exhaust crossover on a daily driver application.
-
The Fel-Pro 1247-S3 for medium riser or the 1446-S3 for low riser ports will work. Steel liners on both of those.

Barry is right, those Fel-Pros work pretty good also, although I've come to like the Mr. Gasket seals better. I was referring to Fel-Pros base line MS90145 gasket and the Squish-O-Matics (Printoseals).
