C1 2x4 intake gaskets
Today I began the reinstallation of my intake for the dual 4 setup , the fel pro gasket set I used for standard single intake was the good black HP set ,
They do not work well for the smaller ports on the 61 intake , I used to be able to get sets that were white from one of the parts stores , they worked well , no longer can find them ! aside from the regular blue felpro sets any suggestions how many block the exhaust crossover , I always have ! The stock intake will be mated to a set of 461 heads .:flag: |
Paragon's gaskets always worked well for me.

I used the blue Fel-Pro gaskets with mine and the 1/2" holes. I don't like blocking out crossovers, personally. More harm than good (rough running, long-warm-ups, diluted engine oil). I had no issue with the blue (other than they stand out) but did use some good RTV for the 'China Wall' sections front and rear. (Toyota black RTV or Right Stuff). The rubber gaskets supplied for these areas on the intake do not work well for me compared to the use of plain RTV.

I too ended up using the blue gasket , we use the black gasket maker works well front and back .
The exhaust I left open this time around . the blue I paint to match were its not covered by intake manifold , Note Photo in post #3 the installed gasket on the 61 . My main trouble ahs always been the small port sizes on the original 2x4 intake , any use of after market has never been hard finding a gasket , for the edelbrock I used a 1205 felpro black . with blocked exhaust . Well its now 14 degrees out garage time is limited . |
Tach drive61, I agree. I am running the same heads you are on my old-style 383. The intake ports on the heads are HUGE compared to the tiny intake ports on the 2x4 intake. Much potential lost, no doubt. But it still screams!

I am glad it all worked out. You have been playing with these carbs for quite some time. Now you just have to get it over to the house and tweak it.
I had my 61 out yesterday, the smell of exhaust made my day!:D |
327 and up gaskets don't work on 265 or 283 intakes can leak water or vacuum
