Rick,

Its all good, I have got going yet so I cant evaluate these Schubeck flat tappet lifters, my engine and use is more race with limited road use, my post wasnt that clear I am suggesting they are a better option in more of a race engine, and possibly a road engine, and less prone to breakage than solid roller etc.
The reason I got KC to install them was for reliability, plus camshaft break in is apparently better!A few guys use them on a street driven engine, but I guess you would go now days hydraulic roller for the street, as a lot of factory cars do, if you dont want to exceed 6800 - 7000rpm! Even with my internals I dont plan on revving this engine over 7200 - 7500rpm.

SFfiredog, speaks highly of Schubeck flat tappet lifters, I dont think these particular steel lifters with the button composite style are designed primarily for 1/4 milers, they are an alternative to solid roller. Weight wise I am running Jesel rockers, but nothing really lightweight as we went for stainless valves. I dont think these ceramic lifters are a lot lighter than steel lifters as the composite is attached to the steel lifter body.
