LT-1 heads # 10128374 max valve size & 4 barrel intake ? 
I have a pair of LT-1 heads # 10128374. I'm looking for a single plain 4 barrel intake. What are you Guys using that is a direct bolt on or modifying ? I'm currently using the GM Performance dual plain intake. Also, what is max valve size for the OEM seat ring. We are looking for a few more tenths next Year in 2013.Thanks for looking,
Ron
