I had nothing but constant trouble with them:

1 Retaining clips were tin rather than a clip and broke several while breaking in.

2 Some Lifters would pump down a few seconds after preoiling and
bend pushrods upon cranking.

3 Some leaked a lot of oil around plunger.

4 Varied in plunger travel a LOT!

I posted about their quality control last year.....Tech line was ZERO help.
Left several messages for Tim Cole and never received a
return call.

Two sets currently residing my weight box.
