ok here is the deal i am trying to save money what do you think about a gsr block with stock bottom end except for pr3 pistons head port polish angle valve job dual springs titanium retainers and type r cams

would stock valves be alright for my stock ecu or do i still need to upgrade to something better because the compressions up i am running low on money is the problem!!

help me stock valves and will my stock ecu still be alright obd2

I would get a tunable ECU. Stock valves should hold up just fine.

The valves will be fine gsr valves are second best next to type-r.Dont waste money or just get the head rebuilt and let them replace them.

no offense but stock redline on a gsr is 8300 buddy so more

and i have the head off i bought a completely new head because mine got thrashed from my lst build so it has nothing in it not even the rocker arms i have dual springs and titanium retainers just trying to get a heads up kinda deal?

i know what it red line at im talking about on a stock gsr haed i wouldn't pass 8100.... but since you upgrade your head i got some bc3+ for sale, you will make good power with good headers..
