348/409 rev kit

I acquired a Isky rev kit with roller lifters for a W motor.. Anyone run them? I may part with them and just go to a flat tappet cam.

Rev kit requires special flat topped tappets for the spring to rest on. Most modern link bar roller tappets have bodies that are not flat on top, having only part of the shell to cut down on weight.

I recommend keeping the roller lifters at the expense of the rev kit if it won't work with what you have. You can run stiffer springs to compensate for the lack of a rev kit (assumes you have screw 7/16th inch dia. ARP rocker arm studs).
