Inevitable follow-up is...Pro seal "sportsman" vs. pro seal "race"?...

I've got plenty of time to decide which way to go...

Thanks for all the replies.


The Pro Series is a "ultra finish" steel top with Napier rings while the Sportsman deal is typically a more conventional Plasma Moly top ring with a standard barrel face 52nd ring with no underhook to scrape oil. Either one I would use up to about 800hp beyond that I would stay with the Pro series.
