"PRW-PQX" Rocker Arms....any good??

I never heard of PRW/PQX rocker arms. Looking at a set for a SBF...they are shaft rockers.
Are these of any quality??...or cheap Chinese/Taiwan stuff??

From my recollection they are Chinese

They work well with flat tappet spring pressures. I have not even attempted to use them with a roller cam valve train.

I went ahead and purchased a whole Jesel sportsman shaft rocker system. Made in USA!!

Jesel makes some great stuff, I just purchased a set for my 347.

x2 I have used their roller rockers on some 230 seat-650 open spring deals and had good luck.

I have used the stud mounts on solid rollers without an issue. Same parts are sold by Pro Comp , Renegade, RPM and others. Some of the poly locks were "soft" and pounded , gaining lash. Changed all of them out and rockers are still fine. 8 years on one set. The aluminum shaft rockers for the SBF had poor quality adjusters. Changed to some used Jessel adjusters ( take out from a Nascar team) and problem solved. About 2 years on those. NO these are not "premium" parts , and you have to substitute some "premium " components but the DO work after that. I am by NO MEANS "pro Chinese parts" but in "some" applications , they are "adequate" and affordable to many.
