The spring can be broken in such a way that it still 'works', just not as well as it should.

That many miles and STILL good compression? That's pretty farking good. A head swap will more than likely bring it up a little more too.... Yep. I'm jealous.

Yeah I have to say I was amazed by my compression results. That's the only reason I'm too worried about spending some moola on the top end.

Besides I've already got the ok from the wife to start ordering parts next week.

That word will get you into trouble. A plugged cat will cause a misfire code for #6 and/or #8.

After checking the price on a set of EQ heads i am now really hoping that its just a valve spring. Cause im afraid i would have to go with odessas oe heads to save some dough. The cheapest set of EQ heads i found were like $300 more than the OE style.

Yeah, about 800 for a pair of the eq, with the 2.02 valves.... vs. around 565 for a pair of better-than-stock replacements.

Where do you want to make your power?
