Roller rockers or Mark Burton sbc rocker conversion for 350

I am looking for a roller rocker setup for a 35o. From my experience the melling stamp steels are made weak and break.

 

lookin' for new or used ?
I have a new set ( TA 1.6 ) but hesitant to sell . saving up parts for a dif motor for later .

 

New or used is fine, just seeing if I can find them cheaper than what TA sells them for.

 

well lets do it this way - keep an eye out for a nice used set , if none pop up then get back to me and we'll go from there . mine will not be cheap but will be less than the current TA price .
