Why ruin a rebuild by initially running with unsuitable lubricant? - you do NOT require any of the modern oils with "super slippery substances" - the motor will NOT bed in with these!!! - similarly do not assemble new parts with the "marvels of molybdenum disulphide" (Molyslip etc.) as such will prevent the grind-off of surface inperrfections... there's loads of SAE 30 "running-in" oils on the market -"Millers" is one such...
You gotta have some friction to remove the sticktion - else the motor will NEVER bed in properly to give a sane lifetime's service.

I am well aware there is contention here - so I checked it out with Bruce Longman (probably the most knowledgeable gent wrt Squares)
It is DEFINATELY the Large bore to Rockers & the Small bore to the Pressure guage!
(Apparently the 4G which preceeded the Mk1 such may not be the case, but the 4G had different pipework).
It matters not what "research" one might have done on the web... nor which "scientist / physicist / enginer" one may have consulted...
For a Mk1: - ROCKERS = LARGE BORE & Pressure guage = small bore
If on a Mk1 you reverse these in order to prevent "over oiling" you are effectively patching over a problem without identifying the source...
much to the detriment of the rockers, the cam & followers... do so at your own expense!!!
Ask youself this question; - is it more important to you that the oil pressure guage should be reading what you THINK it ought to say
or would you prefer to assume that your engine internals are receiving adequate lubrication???
