grumpyvette Posted September 11, 2006 Share Posted September 11, 2006 am I the only one, thinking this is being sold because the necessary extra parts are either far to expensive or not available at all? keep in mind that the heads were VERY LIMITED PRODUCTION, ARE OUT OF PRODUCTION,and cost $3500 plus valves and springs (easily $1000 more) plus (notice $1200) rockers and offset roller lifter cost similar) youll easily have $6000 or more in running heads http://www.jegs.com/webapp/wcs/stores/servlet/CategoryDisplay?lang=-1&catalogId=10002&storeId=10001&categoryId=29850&searchItemId=126765 just the ofset rockers and lifter could cost you several thousand, more and Im thinking ,a small block head with a 319cc port size is not likely to be usable at less than about a 450 displacement our under 5500rpm then, the thought comes to mind, AIR FLOW RESEARCH BIG BLOCK HEADS flow similar numbers but with slightly larger ports and have the advantage of both larger valves and a splayed valve layout, and a larger bore size, so I doubt the flow numbers are at the standard 28" vacume reading or taken with a 4.25" bore fixture which is about max on a sbc aftermarket block Quote Link to comment Share on other sites More sharing options...

LOL. The only reason you make it is to spend it. Think I am going to die broke but happy. Quote Link to comment Share on other sites More sharing options...
