I was just wondering who has seen what kind of gains from running ported heads and intake with the stock cam. I want to upgrade the cam as well but when you add the timing set, lifters and pushrods and a tune to the picture its pretty expensive. The heads have upgraded springs and 1.6rr's so I know I'll get a little more lift and duration over the stock 1.5's but How much is the question. Will the power still fall off after 5200rpms or will it make more power at a higher rpm, etc. What's your $0.02? thankls in advance for your input.

 

I asked about this a while ago before doing my head gasket swap...People said there were very very small gains to be had w/ a stock cam...basically not worth the cost. I dont know about porting the Intake, but thats what I was told about the heads.

 

flow numbers?
