The mention of it getting tight with head on, what springs are you using? Obviously any engine will get tighter when the valve train is all hooked up but it's hard to quantify.
What timing seems to be the best running? The distributor may not have enough full advance in it, leaving you with not enough retard for starting. What distributor?

: What I am describing is a tight engine.
: On the bench without plugs (no
: compression) it took about 30 ft-lb to
: turn the engine over by hand. It was
: significantly lower than that when the
: head was not on and there were no
: springs to compress. I did check all
: the clearances prior to final assembly.
: Rod and main bearings were both coming
: in with about 0.0015" running
: clearance (checked with Plastigage).
: So I really don't think I am dealing
: with a mistake during the build.
:
: When I advanced the timing to
: experiment with getting a smooth idle I
: knew I had gone "too far"
: when the engine would not turn over
: when attempting a re-start and would
: occasionally kick-back. I am confident
: that the present issue is a tired old
: starter motor and an engine that has
: compression for the first time in two
: decades.
:
: Jim M. also asked about the PCV valve
: and its connection. At the moment I
: have a new-old-stock PCV valve. I
: never trusted the old one and bought
: this one to insure I was starting with
: a clean slate. It certainly would be
: easy to plug the manifold connection
: and see if this has any impact on the
: idle vacuum readings, but after last
: night I was able to get the engine to
: develop about 11" of vacuum. The
: pundits say that the S2 cam I am
: running will typically produce around
: 13" at idle so I am not that far
: off now.
:
: Thanks for the continued suggestion. I
: plan to re-torque the head over the
: next few days and if the weather
: permits I will work on getting the
: carbs better dialed in to work with the
: rebuilt engine and new cam.

: Hi
: Not sure if you are describing
: "hard cranking" with ADVANCED
: TIMING (draws alots of amps) or you
: feel the motor is tight! (you would
: have felt this on assembly)
: THE OTHER thing - you may have done
: (that would cause stalling when
: driving) is to use the wrong MK1 fuel
: pump !!! Please talk to us as to what
: was used ( and or ask what to look for
: in the difference) Mark
