Blocking Off Exhaust Crossover

[67428GT500]

I apologize if I missed any responses.  On the Fel Pro 1246-S3 and 1247-S3 intake sets they have a metal core and the heat crossover is blocked off.
I used the 1246's with the 2.34 port heads on my Shelby.

Resurrecting this post. I'm going to install a F427 on a 390 I have lying around and put it in a '78 F150. I've never used an intake with the crossover. Does anyone have a good picture of what they did? I can picture the piece of sheet metal but the butter knife? I'm just throwing parts on hand together for this engine. Trying to see if I can use a Fel-Pro 9781 intake gasket as I have about 10 sets lying around.

Thanks,

Doug, all I do is cut a piece of 18 gauge sheet metal into the shape of the hole in the gasket, and RTV it in place over the exhaust crossover hole in the head.  Never had a problem doing it that way - Jay

Thanks Jay! Last night I laid an intake gasket on a head and I see it now. Pretty easily made. I guess you want to make sure that when you install the filler plates and intake that something doesn't slide and stack up.

I happen to have .010" stainless shim stock which works well.
