Has anyone used PRW rockers ?

I need rockers for 440 source stealth heads , my machine shop said he thinks they are decent just wondering if anyone has any feed back i see a stainless alloy and an aluminum , i need the 1.5 ratio if i thought stock stamped would work id look for them it would save a bunch of money

I haven't used them, but have seen friends blow them up. If you cannot afford the Harland ones, get a set of ductile iron or similar. Just my opinion, but never skimp on engine parts.
BTW, the aluminum ones are the ones I've seen shred.

i don't know why the stock stamped wouldn't fit. i probably wouldn't use the stock or alum prw's on heavy springs and an aggressive high lift cam. the ductile iron won't break but do have fulcrum issues over time.

Get a set of iron Ductile from crane or Comp and be done.

How much cam/spring are you running? We stuck on a set of MP's heavy duty stamped rockers on a small block with a .480 lift cam and turned it 6200. Only has about 30 passes but so far so good.
