Well, you allready did your bottom end and now the heads! You could just take them off drop them off at the mashine shop and for around 150-200 bucks have new heads. I'd say bite the bullet and do it! just get a second oppinion that that is the problem your having. You also could have a bad camshaft lobe or a bad rocker arm, the puchrods tend to wear so bad that they eat them self through the rocker arm.
