    “… the PCV is fixed so it is open always but the hole is less than 1/8"   I hadn’t heard of doing this before, what is hoped to accomplish by doing this?
    14” idle vacuum seems low, unless running a hot cam, I would think you should be getting 16-18”.
    Were the heads milled at all?  When milling the heads, the intake manifold sides may need to be milled to account for the heads being sitting slightly lower on the block.  Sometimes people would use two sets of intake manifold gaskets to account for the change.  If this is an issue, it can cause the intake ports to draw oil from the lifter valley … just something to consider.

    Bob yes it is a hot cam and no mill work on the heads. The PCV was changed to the fixed orfic type to help the IAC on the Sniper to keep the surge down at idle, and it did that. I think we found that the valve seals are in fack the problem here but will do a leak down just to be sure. Check out the new pic too. Its a work in progress with a new engine.

    check out the rear plugs and you can see my oil smoke. And there are no oil leaks on the outside of this motor like gaskets. The heads are dry and as clean as they were when we install ed the plugs.

    LOL 6Sally6, you are so funny. Did all that. But today we discovered the leak down test was great with no leaks. So i got the seals and took one off to change and discovered I have special seals problily due to the bigger valves. turns out they are Pioneer OS 1045 seals and i cant find them anywhere. I will go to the shop in AM and see what they are going to get me. I measured the valve stem and got .339, and the guide was .477ish. Stock umbrella seals wont fit inside the valve spring. I did find som Trick Flo seals at Summit that mite work and ordered them.

    Cab4word67 – from the dimensions you provided, you have 0.138” valve stem to guide clearance. Seems a quite large.  Here is some OEM info from the 1966 Ford Shop Manual for the 289 engine.
    Valve Stem Diameter:
    Intake: 0.3416-0.3423”
    Exhaust: 0.3406-0.33413”
     
    Valve Stem to Vave Guide Clearance:
    Intake: 0.0010-0.0027” – Wear Limit: 0.0045”
    Exhaust: 0.0020-0.0037” – Wear Limit: 0.0055”

    Re: I just love this, NOT

    These are built, ported heads, big Chevy valves, yes Chevy valves.I think they are 197/160s but not fully sure.   I got the new seals installed today and guess what. Oil seams to be going away, it was very hard to see if any at all. Seals were toast. I have new Viton seals now and they fit well even over the machined guides. The old ones sorta fit sung but slid off the stems like they were never tight.
