    Default Cylinder head replacement

    The valve guides are leaking on my 84 Crossfire and was thinking of purchasing a new set of Edelbrock Perforer heads #60909 and was woundering if this is the way to go or to just have my origional heads reconditioned. I really would like to pull some more HP out of this setup if possible. My question is simple has anyone out there with a crossfire setup tried this?

    I am sure there are cross fire owners who have replaced there heads. Did you talk to whalepirot, I think he has a modded crossfire. Good luck with your search, unfortunately I cannot be of any help.

    when you say the valve guides are leaking??? do you mean that the oil is bypasing the seals??? These seals can be replaced without taking the heads off...

    Valve seals are replaceable w/o head removal. They leak oil. Guides are brass and hold (guide) the valves.

    Many moons ago, I had my stock '84 heads worked by a great shop nearby (Bob McCray- local, successful drag racer). New guides, seals and a three angle valve job topped some mild flow work, plus I had them redone for 2.02 intakes and 1.80 exhaust (if memory serves). Not too pricey. That, a mild cam and headers was great for a while, but it really needed more chip work to reduce the rich running.

    One real issue with the Crossfire is the stock manifold's small openings, which are not too easy to modify (enlarge). Hence, the L83 runs out of ooomph (restricted airflow) in the mid 4000's. Unless and until you find a way to get more air to the heads, too much work on them is of minimal value.

    More induction solutions are available now than were before I swapped to a TPI (major job; not recommended).
