It depends how hard you're going to push it.
I would certainly say you want to be within 0.025", or 0.001" in English

Vf28 and appropriate mods (ported headers, inlet manifold spacers, ported heads and inlet manifold, 3 port boost solenoid, 3" exhaust, samco inlet pipe, FMIC and induction filter the oligatory Walbro and PFR7B's) i am hoping for about 340bhp with good drivability in the end, so the engine shouldn't be running that hard i don't think.
I will shim them to within 0.025mm then, cheers R19KET

just had a look on their website and they do actually sell precision feeler gauges, will be looking at them i think, a phone call will be in order just to make sure.
Thanks for all you help, much appreciated

Hi there,
I have a impreza sport 2.0 (non-turbo) my98, what type of valve adjustment do these have?
I have a tapping noise coming from the nearside rockercover and would like to know what im looking at when i remove the cover.
Any help on how to check and adjust would be most grateful.
many thanks
Russell
