Would there be a usable performance gain from the following head setup on my 2.0 block? (WITH BIGGER INJECTORS AND AN 18G)

HERE'S what the heads come with:

2 x WRX Cylinder Heads with valve covers and gaskets
2 x STi USDM VERSION 8 CAMS
16 x STi V7 jdm valves (Already Installed Inside)
16 x STi V7 jdm Shimless cups (Already Installed Inside) NO MORE SHIM'S
16 x STi v7 jdm Pink Valve Springs (Already Installed Inside)
16 x STi v7 jdm Valve Keepers (Already Installed Inside)
4 x Wrx Timing Gears (2 intake 2 exhaust)
4 x Cam Seals

Valve clearance:

020in on intake
035in on exhaust



Could these heads/mods be protuned for with an accessport?????

ALSO: In the future, could I use these heads with a v7 2.0 sti short block? Would THAT require a new ecu???

Thanks!

Pink Valve springs?

I don't think you'd really gain much. STi cams might give you a little extra punch, but not much. All that is really being upgraded there that I can tell is the cams. You have a 2005 so your heads should already be shimless cups. And the WRX timing gears and cam seals and such wont make much of a difference. ANd I don't think STi valves are any bigger than stock WRX valves.

You might as well just keep your stock WRX/92X heads. or spend your money on some substantial headwork.

You bought that guy's heads or you're thinking about buying them?
