Mancini Stainless Steel roller rockers

They are notorious for it, the early UNBUSHED ones. They are frequently for sale on Ebay, scuffed. They can be bushed to repair/update them, of course, which is what Comp Cams eventually did. Who knows if unbushed ones might live with proper oiling or better quality oil, etc. I have even seen a few unbushed Iskys or iron W2s that were scuffed so....

273 could scuff.
Must have the correct shafts that have the oil feed holes in the right places to oil the adjusters, pressure point of the rockers bore aimed towards the spring.
I did buy mine cheap in 2006, like new $200 in murrieta ca...same day grabbed a rpm intake for 75, like new. Was a good day.
I've run them ever since. I replaced the Ohio crankshaft rockers with the comps.
I have some bushed 273 rockers as well from mopar performance "bushed for over 7000 rpm" with isky adjusters. Good stuff.
I also have some older prw,the flared pin roller ones. They dont clear springs with a od bigger than 1.460
