I see 2 different part# for the LT1 OEM lifters, 5234890 for '94-'95 and 17120735 for '96-97.
I read something about the newer ones have a different check ball or spring pressure....are those ok to use in a '95 application? I assume so since there should be no other differences, but whats the advantage of the newer higher spring pressure lifter?

Is there a part# for either one of these as a set of 16?

 

Why don't you just go with the LS7 lifters? Part # 12499225 and they are only $99 at sdpc.

 

I've got the Caddy Racing lifters now and they are too darn noisey, have read the LS7 have been noisey too. Have OEMs in the truck and they are very quiet.
