    06 4tec 155 Head question - It has different valve seals & guides?!?!?!! Help!

    I purchased a complete head on eBay about a year back, its from a 155hp 4tec. I thought it was an 07, but after looking at the head more closely, and by reviewing the auction I believe it to be from an 05. Anyway check out these valve seals, and valve guides. I take it I probably don't want to use these on a forced induction engine? Since the RXP seals are held down by the valve springs, and these just snap around the valve stem. Can I use these in a SCIC motor, or should I have them changed out??

    Has anyone seen these before? Or used a head with them? I coincidentally bought a complete set of new in the bag RXP valve guides on eBay a few months before, (for like $25 total! ) so I can have the guides replaced. I just wanted to share this in case anyone else runs into it, as I have never seen, or heard anyone mention these before. By comparing part numbers, they appear to have only been used on 05-06 155hp models.

    Please forgive my blurry pictures. I have a bad habit of getting things wet lately, my camera hasn't worked very well since.

    Someone has to know about these different valve seals? Can I run these on a boosted motor? Or am I asking for trouble, and should have the valve guides replaced?

    Should I give them a try? What's worst case scenario?? I REALLY dont want to have to swap out valve guides. I have a good machine shop that will do it. Just prefer not to unless I have to.

    Someone must know whats up with these valve guides/seals

    Bump, surely someone has come across these before. Are they inferior, or just different???
