Hi Joe,
I went through the same thing. I asked for the spec's from the supplier
I purchased them from & he wasn't sure, then I asked all the suppliers I
could ( TRF, APT, BPNW, Moss ) but they either didn't know the answer or
said simply make it a mild interference fit. It seems many of the parts
houses like TRF out source this procedure. I eventually left it up to
the machine shop I used & his experience machining race motors on
american iron. I guess his educated guess was good since the last
20,000 miles or so have been reliable & oil pressure reading are still
the same. When I was assembling the motor I slid the cam into place the
fit seemed perfect.
Sorry I can't be more specific.
