Roller Rockers in Stock

Exactly what I was told...5-6 years ago...when I was running 10.50 - 10.60's in D/S...by those that were 3 tenths slower than me.
It's almost funny. You guys will scream about roller rockers but not one of you are screaming about $850 BBC rockers with 9/16" studs or $500 to $850 Tool steel or Schubeck / Smith lifters. And the $950+ billet steel cam cores on 50mm or 55mm journals are silently ignored.
Maybe, just maybe, those with the exotic stuff, don't want the little guy that can't afford the trick stuff to "catch up" with the allowance of roller rockers or their $89 lifters and $150 camshafts?
Any of you break a rocker in eliminations at a NHRA national event? I have. Lucky it was my bye run into the semi-finals. Had there been somebody in the other lane, I would not have made it to the finals. And lucky I had my bucket of spares with me too. My runner up finish was over $5,000 in winnings. I don't think $279 rockers sound like a lot of money when stamped rockers breaking can keep you out of the next round.
And I'm sorry, but NHRA didn't allow crate motor factory Super Stockers in Stock 30 years ago either.
Allowing standard $279 Crane Gold type rockers in Stock is actually good for the little guy. And so are a set of solid lifters with EDM hole oiling for around $89 over the $850 composite lifters and $950 billet cams.

I would agree. Not to mention, everybody is talking about the added expense of roller rockers. But just how much has the stamped steel rocker costed everybody that broke them. Because normally when you break a rocker you have other issues as well, especially if you are running the compsite type lifters. I'm sure that a stamped steel rocker has costed more than one person a complete engine. The rocker breaks then the compsite lifter also breaks at the same time due to not being controlled at the cam. Then you have all that junk going through everything. All from a stamped steel rocker. Now its not the rockers fault. They weren't designed to run at 230# on the seat and 600# open pressure at 8000rpms so. What do you do?
