Heat crossover ????

What he said; just cut a square and cover the hole......when I did mine, I cut up an old coffee can

I can't help myself.......a man of your intellect couldn't problem solve this..........yikes!!!!!!!!!!

LOL...forgot to mention I usually REMOVE intake manifolds with heat crossovers in them, and if I, stuck with it, I use a paper gasket with the steel shim to block it off.

Trying to get this done without machine work if at all possible.

May have to start looking for a coffee can.
