Stage 6 heads

These are on my 470. Short block is supposedly sold. So I have these for sale. Their still on the car. It will be awhile till I get them off. Not very good pics but this is all I have for now. Going to a RB stroker so the supporting cast will likely be for sale also. MP. blue roller rockers. Smith Brothers pushrods. MSD dist TM7 intake or Weiand T ram. CPPA 2 inch under chassis headers. Block and heads have to sell first b4 other goodies are for sale. The heads have been ported but I don’t have a flow sheet for them. They flow 320/260. When dynoe’d the engine made 655hp and 620tq. Had 108 volummetric effenciency Heads are $ 1400.00 usd. Plus shipping. U can buy the rockers, pushrods and possibly the MP valve covers with them. Thanks. Kim

Hey there! Interested in these heads but know nothing about them.. Are these a bolt on replacement and go or is the valve geometry and spark plug angles all different and all from say a factory 452 head? Could i use my factory rockers and shafts and all? Also, are these as good or better than the aftermarket heads available like edelbrock or trick flows etc.? Sorry for the questions, just dont know much about these. I have stock 452 heads now and want a much better flowing head.
