Looking for stainless roller rockers was looking into prw but than saw speed master for alot cheaper but they look the same anyone use either of these ?
440 with flat top kb pistons edelbrock 75cc heads ported polished luniti 513lift cam would like to do 1.6 rocker arm ratoo to up the lift a little bit and yes I need new pushrod as week but won't know what size untill I get rockersDo you need an adjustable roller rocker? They (most and that depends on a lot) are not a drop in. You need to verify the geometry and push rod length. Tell us about your build or what you'd like to do.

I have PRW stainless 1.6's on my 340. Upon inspection, one had a messed up bushing. Other than that, they were a great value and are working flawlessly for me. Don't let others who have not used them talk you out of anything. Listen to those who have actually used the products you're asking about. To me, first hand experience trumps the internet experts. I have no experience with the speed master rockers. Either way you go, even if you opt for higher dollar rockers, inspect the hell out of them before bolting them on.
I listen to those who have used them. Mike from MRL and Jim Laroy, the guy from B3, Brian from IMM and on and on. All of them have posted pictures of how crappy the geometry is and how bad the quality is. All of them build engines for a living. I trust their word. If I have five grand in an engine, I sure as heck ain't gonna run 200 dollar rockers. I am also not going to advise anyone else to.
Glad you've had good luck with them. Everyone is not as fortunate.
Funny you mention Brian at IMM because he's the one who actually recommended the stainless PRW rockers to me after building me a set of heads and knowing the rest of the build. As with any rocker you'd buy from anyone, you just have to inspect them really well before bolting them on.
I just hope the OP can read through the BS on this site.
