I was going to extensively port the exhaust side and change the exhaust cam to a slightly larger cam to increase flow on the exhaust side reducing pumping loss on the exhaust up stroke. The engine made good power but want to make it more efficient and perhaps get 550-570RWKW on premium fuel. What gains ahev you guys had with ehad work? No doubt the efficiency will increase power output but wanted to get some feedback from someone who has actually had head work done. Link to comment Share on other sites More sharing options...

Most big power streeters are just going for a simple clean up and match to gasket style. DLM and 6boost have been getting into it on the BIG power drag cars if that helpsThis thread has some secret info in it! http://www.fordxr6turbo.com/forum/topic/63278-project-manual-typhoon-9-sec/ Link to comment Share on other sites More sharing options...
