Two heads, one block

Hey, new to the forum found a lot of good information on here, my problem is I bought a 95 f350 and I'm getting blue smoke out of the drivers side exhaust (true duals) I've replaced the pcv valve, changed the oil and added a quart of Lucas, compression is good 150 150 140 130, just replaced the valve seals today and still smoking. Got to doing some looking and I have an f3te head on the drivers side and an e7te on the passengers, can this be causing any problems or hurting anything? Any help would be appreciated

The F3 will flow a little better. But is the same cc's and no it shouldn't make it smoke.

A new seal won't stop a worn valve guide from leaking oil into a cylinder. It might slow it down for awhile, but it won't cure the situation. A worn valve guide allows the valve to wobble as it goes up and down. When it wobbles it pushes unequally on the sides of the seal. That allows a little oil to go down past the seal. Since your compression is pretty good, your bottom end is probably fine, but I think you have a worn valve guide.
