About using hot water to warm up the intake, i am confused also. I read article from Tom from the stovebolt engine company and he says yes. I talked to Patrick from Patricks antique cars and trucks and he says no. Maybe its because of where i live. I live in Las Vegas where it gets hot but in the winter sometimes it gets cold believe it or not. Where you live might be a factor to consider. My 2 cents
