The shaft is definitely the right diameter. I will again check to make sure it has good oil flow but I blew air back through the head and I could hear it coming out down in the block so I'm pretty sure it's going to flow oil.
I'm sure the rockers were not worn when I bought them at least not enough to make a difference. I noticed the other day when driving it the oil pressure was down around 20 psi at idle hot and that was the lowest it's ever been. Probably in part because of the huge clearance around the rockers. Otherwise it's about 60 psi at speed.
P.J.

: Right, I'd forgotten you got these
: rockers from me a while ago. They ran
: a couple of seasons but should not have
: had any unusual wear. I've got another
: set on the car, 1.55:1, which has
: probably run five seasons now with many
: more race outings/season with no
: detectable wear.
:
: coil bind - I would have guessed this
: would bend a pushrod before it wore out
: the bushings. there's not a lot of coil
: clearance at full compression, so the
: .08 sounds ok to me.

: If, when you were priming the engine
: with a drill, you could see oil leaking
: out around all the rockers from the
: shaft, than you know you have oil flow.
: I usually prime the engine with the
: valve cover off to look for this.
: Probably worth checking this one more
: time if you didn't already verify.

: Are you sure the wear happened when you

: I'm assuming there's only one diameter

: .080 is plenty of coil clearance.
: The only other possible point of

: P.J., what brand of roller rockers do
: you
: have? I assume by "holes
: down" you are referring to the
: rocker shaft and the oil holes in it?
: My recollection is the orientation of
: that shaft is set by the lock screw
: (philips head) in the rear pedestal
: that screws into the shaft, and thus
: the oil feed holes through the head
: into the rear pedestal and then the
: shaft are correctly aligned.
: Question - have you confirmed you have
: good oil flow to the rear pedestal,
: though either the block passage, or an
: auxiliary oil line from the main galley
: to the tap in the left rear of the
: head? Usually the concern with these
: aux lines is too much oil flow.
: Assume you confirmed the shaft was
: clear of obstructions by blowing air
: through it before you installed?
: Hardened shaft?
:
: Hi Scott. When I bought these you told
: me they were Harlan Sharp rockers
: 1.45:1 ratio.
: I have confirmed that there is good oil
: flow through the aux. line at the back
: of the engine. I primed the engine by
: drill prior to initial startup. You are
: correct about the Phillips screw that
: locates the shaft so I suspect that it
: was located in the proper orientation
: .. The shaft was Tialn coated and is
: very hard and therefore undamaged..
: Is it possible that I could be
: experiencing coil bind with the valve
: springs?? Nothing seams abnormal and
: there is about .080 between the coils
: at full lift but I don't know what
: there should be for sure..Thanks P.J.
