Kind of a multi-topic post, but is there any cam specs and head flow data? I have an '08 head which is at the machine shop to get the exhaust side ported, and will be doing 2mm oversized exhaust valves. I'm looking for 7500-8000RPM in a turbocharged application for my Supra. Would the intake side need to be ported as well to make any power up there? Would I need the 1mm OS intake valves? Also since the intake cam in not VVT controlled, does anyone have any on-paper gains at higher RPMS by clocking the intake cam back a tooth? Maybe an adjustable cam gear would be beneficial?
