Tidgy Posted January 18, 2017 Share Posted January 18, 2017 I'm running a full supertech valve kit in mine, valves, buckets etc etc etc Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted January 18, 2017 Share Posted January 18, 2017 Although supertech stuff is good quality, I was advised that the oe stem seals are good for 500 hp +. Especially if you use the exhaust valve seals on all the valves (intake valves too) ,as the exhaust valve stem seals are made from a better quality vitron rubber to cope with the heat compared to the oe intake stem seals [emoji6] Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted January 18, 2017 Author Share Posted January 18, 2017 Yes, did read that savs, may order two sets of supertech then and use them on both, maybe the seller will do 16 exhausts Quote Link to comment Share on other sites More sharing options...
