<VV> regular gas and fuel economy in a 110hp corvair

I meant to put .042 copper head gaskets in my 110 hp powerglide 4 door that
pinged rather badly. By mistake I ordered .052 gaskets but since I wanted
to get the car on the road I put them in anyhow. Result? Maybe I lost some
horsepower - I don't miss it, but I use 87 octane and can hardly get it to
ping even in 95 degree weather. I have been driving it that way for about
10 years now. Just my experience. Dennis Dorogi
