need engine help bad
Okay i have a built 2001 gs it has:
Cold air intake
crower cams stage 1
aem cam gears
header
je pistons 10.5 to 1
bored out .30 over stock
jet performance computer
Stock valves and valve springs
stock rods and crank
I am wondering if the higher compression will cause major valve chatter around 20 to 40 mph or could the computer that Jet programmed be advancing the timing causing the chatter.. Do i need vavle spring and retainers? I need help
thanks

been there done that
definitely get something programmable. if you're valves are making that kind of noise they need to be adjusted. you will only need the springs/retainers if you plan to take it above the stock rev limit. which i recommend you do not.
