72 Thermoquad 6138s

I had one warp on me in a non stock application. Easy fix as described above.
This is not to throw crap at Bobby (RRR) What he wrote is true, it is the high heat that warps the bowls, hence my saying "Use the thick OE type gasket" as to help remove heat from the carb. Less heat on that item the better no matter the manufacturer of carb.
