: Hi Guys,
:
: I have a set of Clifford single valve springs
: w/damper. In the Mopar Performance book it
: mentions that you don't/can't use the
: umbrella style viton seals with dual valve
: springs. To me, the damper doesn't
: necessarily constitute "dual
: spring". Or does it?
:
: OK here's the question. Will the umbrella seals
: fit, or do I toss them and cut the guide for
: the teflon seal? This is going to be a
: street engine, so I think I'd prefer to use
: the umbrella seals if possible.
:
: Thanks in advance for your help.

: I'am with you. Single spring with damper is not
: dual springs, so the umbrella seals should
: fit with those springs.
: Here's something that I do whenever I finish a
: head, just for extra insurance. I use a
: vacuum checker(Sioux) to physically check
: the seat/valve face and stem/guide seal.
: It's kind of like a negative pressure
: leak-down test.

: Sioux, Vacuum checker, where from, do you get
: these marvelous toys? I thank you!

: I got mine from Western Equipment in South
: Everett, Washington. They are an outlet for
: Goodson, an auto tool company, and Sioux
: Tools. Either of which sell such a tool. But
: any Sioux tool outlet can hook you up.
: I don't have the catalog #, but it is a kit
: with several adapters, a case, and a cast
: aluminum handle/with guage and compressed
: air inlet. The compressed air runs across an
: orifice in the handle, which creates a
: vacuum that is connected via the adapters,
: which are sealed to the head's ports, or
: spark plug hole. If you buy an additional
: adapter big enough, one can even check ring
: seal with the head off.
