Tim, I installed a set in my autox / street TR4. The pistons were much

can't quantify "much") and came w/Deves rings. What's not to like? I
ported and cc'd the head and shaved it to 10.0:1, which works fine with
what passes for premium pump gas. The cam is an Isky 777. With all
those bits, and 40 DCOEs that are waaaay too rich at the moment, I can
light the tires in second gear. Hehehe I forgot to mention that I'm
also running BFE's oversize and gas-flowed valves (Ken's valves were
almost too pretty to install). This engine pumps some *serious* air!
While you're working on your engine, why not have the crank nitrided
(I'm assuming you're using a stock crank). Shaftech did mine, and it
now rings like a bell.
