I have always used Manley valves in the past. Does anyone know if they are still made here in the states or overseas. The severe duty (NK844 and the XH428) material is what I have been using.

I probably have to take my 4.600 bore BB chevy out to 4.625. What head gaskets are you guys using. I have some Fel-Pro 1057 that are 4.630 bore but on the notes on the package they do not recommend for the 4.625 bore size. Any thoughts please. Thanks

I think the combo I have is a little weak and I think with more power or better combo the convertor would fl...
