The engine builder I use said he has successfully used Total Seal TSS rings that have gapless second rings in some customers street performance engines that have a maximum of 10.5:1 CR but without nitrous or forced induction.

In 2009, I considered using those rings in my 1963 Pontiac 455 Catalina but I chose to use conventional Speed Pro standard tension rings instead.
