i agree with the Comp crap. they have changed thier lifters recently and are crap. they used to be silver in the middle and have CC lazer etched in there and an extra ring cut around the top. they looked good. now they look like the 100.00 dollar cam kit ones. no name just raw cast in the middle. i have 4 that are clicking. one that was stuck in the bottom. had to hone the piston in it to get it to move. it is still sticking till full oil press. hits it.
called them they say pull the cam and send it all to them. they should send me some new lifters so i could take the parts out of them till i get a working set.
