Re: Can You Shim Valve Springs Too Much ?
sounds like it's time to get the heads machined for screw in studs and guideplates. probably need the flat guideplates, but you'll also want to have the pushrod passages thru the heads drilled out to 1/2" also.
about $125 around here, but the heads have to come off.
