TF Heads Question?

[Thad]

I'm not sure. The heads were already on the engine when i bought the car. The noise has only come about rescently. I've sat and listened to it and there is a tapping coming from the right side towards the back twoo cylinders. The other side sounds like normal valve noise. This is why i'm thinking there is something a miss with the roller rockers or valve assembly on that side. i'm trying to avoid taking the heads off but if i have too i will. Can assemblies loosen up in the heads though?
