I plan on getting oversized valves and upgraded cams for my evo 8 head. The only porting work I was planning was the increased valve port. Which are the best bang for your buck valves and what supporting mods are needed with oversized valves. Also which cams would be the best size for a +1 valved, 2.4L storker, running 20-30lbs of boost?

 

what size turbo are you planning to run?

 

currently have a Turbonetics T3/T4 50 trim, .63 hotside, Stage 3 wheel, ball bearing, but am probably going to get a bigger turbo.
