Plenum Port + Standard Gaskets = Bad Idea

[rhipsher]

I would not use glue for the simple fact that I'd hate having to scrape it off every time I put new gaskets on. What a pain in the butt.

Those fenolic spacers are interesting (might have to look at that if my gasket problem returns)... I heard a rumour that the cooler Plenum/air temp is worth 20HP?

Only pointed downhill on a 60 degree slope. In Short Hell no...

They do make the plenum much cooler. But not 20 hp cooler.

I personally like the idea of just tapping a thread in the coolant hole to block it of myself. Using the spacers is more work and you have to cut 4 gaskets instead of two. But it's always worked very well for me.
I just go down to the auto parts store and just buy a sheet of .062 thick Felpro gasket materiel and I use .048 thick for my throttle body after I top end ported my car. And just use the spacers to trace out the pattern. But I also have the spacers marked face 1-2-3-4 so they go back on the same way I blended them to the plenum and IH housings.

Rick,
Is that a pubic hair on the top drawing left side port? You guys must be getting slopping in your shop again

Lee,
You know that checking relieves all doubt. We can only be guessing till the tale of the straight edge is told. Not pointing any fingers just stating what "I" would do.
You do great work and you would NOT have let anything like this slip past you

Wow, that is interesting. Because both heads and plenum are ported on mine and I trimmed to match and although very thin in the middle and no glue or adhesive never had a problem like that. I blocked off and bypassed the coolant so that may have helped. I trimmed OEM gaskets though. Glad to hear you got it resolved.

[LGAFF]

I just want to make sure its right, I am not a PC expert.....so if there is a chance they are warping want to know how to avoid it, etc

No! It's one of my big black butt hairs.
