engine problems

[quickinda6]

Hello All, New poster and long time lurker, I'm having this problem with my 87 gn. i had a valve cover gasket leak on the pass/side. so i changed it twice. make a long story short when i pulled my exhaust manifold i noticed oil in the exh ports of the head on the 2 and 6 exh ports. so i did a compression test on the pass/side and i came up with all the numbers reading between 125-135. so i removed the rockers and applied air to the cylinders and air is pouring out of the exhaust ports on the heads, i dont know much on the engine it might of been toyed with. its mostly stock and milleage unknown.
Thanks
Vinny

Sounds like you need to take the head off and find out if there's a problem, but if you've got air escaping you probibly do.
