Intake install help- pic

good thoughts going on in this thread.

no, you don't use metal gaskets with aluminum intakes, any success in doing so would be contributed in absolute perfect alignment/tight fit/ =a miracle unless everything has been machined perfect compensating for the loose factory tolerances but wait....the factory used metal on big blocks....now it's down to the intake and corrective machining.

I rebuilt a 340 .020 over,x heads, just milled .004 thou off all decks and used an un milled LD340 w/metal gaskets that lined up good with the bolt holes...it blew smoke out of the pass side exhaust pipe....

I copper coat all the big block intake gaskets and let them tack, or they get hi tack painted on.

2. The cross over is for faster warm up/egr/heated choke, and as long as the carb is attached to a warmed up running engine, mech fuel pump absorbing heat would help, the carb shouldn't ice...it would have to be pretty fk'n cOld, colder then cali.

3rd, if you don't use metal [like a cut piece of oil filter] to block the cross over...it will burn right thru in no time, and u'll notice the loss in torque too.
