Strip yer lifters!

Following some advice I read on here I just finished taking apart and cleaning a set of SBC hyd flat tap lifters, brand new, Speed pro cheapies. I imagine someone on here could tell us where they're being made now, but I don't care--it's the last set I buy. In 16 lifters I found 6 with the valve plate in upside down, one with 2 valve plates in it, and one with a nice shiny chunk of brass under the piston. In addition 3 or 4 had really sloppy machining inside where you could see the drill had galled at the bottom of the hole. I don't wanna put these things in my engine!

Our Buick's have a bad problem with eating cams anyway. Plus the oil companys took out that zink and it wipes too hard on a flat tappet.
GM lifters are more expensive but have a nice hard pad on the bottom so you don't fish bowl them. That's what I'd buy if it had to be flat tappt.
Good luck,
Scott~

Right, GM part #12371044-16 for a set of those. That's what I'm getting.

interesting all the speed pro lifters I've used have been A#1. I did hear some of their piston line is being manufactured in India now but I have no proof of that.

AC Declo lifters, not sure of part #, are still excellent.

I have rollers. I was commenting on AC Delco being cheap in general to the general availability of other brands. I paid $120 from Scoggin Dickey for roller lifters. Compare at $600 from GM Performance.
