Ted,
As Charlie said, the valves on later models like the 850 are bigger, they
will not fit the V700 heads. Some of the early 750's used the same heads and
valves as the V700. Rather than machine a good set of V700 heads, look
around for some later model ones. Plenty up on eBay all the time.

Fifteen years ago I changed the heads on my Ambassador, Header pipes were
moving arround Threads were toast! Put on new heads and kept the
valves.These old valves fitted into the V700 heads! Is that right? Will 850
eldo & 850 t valves fit or are they bigger? For sure the twin springs will
not fit over the vavle guides. Guides have to be changed so should I machine
the heads to fit the dual springs or just leave the singles? Thanks for the
help Guy`s

Hi Ted,
I wouldn't think there would be a problem with the single valve springs
unless it was with float at high RPMs. The V700/early Ambo heads also
have smaller valve diameters so you'll not get the horsepower of the
later heads. They use a different guide as well, but the later style
will work without the locating circlip or ridge. One plus that I've
noticed though is that the V700 heads don't seem to crack between the
(intake or exhaust? - can't remember right now) valve and sparkplug hole
like most of the later heads do. If you use them I'd recommend using the
reducer inserts sandwiched between two gaskets for proper port velocity
and heat isolation. Cheers,

Hey Guys I have a old set of heads that came off a 700 or 750 with the metal inserts for intake side. When you have the inserts out the intake hole is too big for the newer square sided carbs. Are these heads as good as the others. Looks like the dual springs will not fit . They have good exhaust threads! Any problems with the single spring valves. Thanks Ted |
