Have an 87' GN with newly rebuilt motor(1100 miles). Ported/Polished, bigger cam, K&N filters, new MAF, high flow oil pump, bigger adjustable fuel pump 3" down pipe, 2 3/4 exhaust and the rest is pretty much stock. The problem or not is it sounds like the lifters are pecking in lower mph and lower rpm. I am running high octane but not racing fuel. Like I said it runs great.Second, do the heads need to be re-torqed any time soon? Have changed oil at 500, thats all I've done(builder gave me diesel oil to use first change)(Ever heard of this). And the last thing for now is what oil is everyone running and additives? I've seen alot of different things people have said to use, but what's best for GN'S? The reason I don't ask the motor builder is he got p.oed because I thought what he charged me for the work he did was somewhat ....well way to high. Now the jerk won't return any calls and if it blew up probably wouldn't honor his warranty. Anyways, if anyone has dealings with anyone in NC write me I'[ll lead you away from him. If I could get a little help it would mean alot.
