when you test your compression and it comes back almost perfect, does this meen that the rings should be fine? i am having blow by somewhere and i have narrowed it to valvestem seals or the rings and i am wondering if the compression would be affected by either one of these.

 

Almost perfect compression usually means your engines internals are in good shape. I would say its not the rings, as bad rings wouldnt show next to perfect compresion results.

 

but yet i have a rebuilt head. so it shouldn't be the valve stem seals should it?

 

How do you know that there is blowby? Its pretty hard for you to have blowby if the piston rings are sealing correctly. You can't have blowby through the valve stem seals b/c blowby gasses are defined as "Oil vapors and other emissions that leak past the piston rings into the crankcase" (modern automotive technology).
