Hi "J", close on the diagram but let me add to it some with one direct from Isky (below). Just appears slightly more accurate??
(Add) Probably the main reason for us not seeing any "flat" style lifters over the years is due to the fact that when a unit comes in here for a build just about every old piece ends up in the dumpster unless the customer wants them back! Cam, lifters, timing gears, pistons, etc ALL in the dumpster! By the time these pieces get here they have "outlived" their intended useful life for the most part!
On a side note, this (flat) style lifter MAY be the sole reason Ford went over to the rotators on the valves, just an educated guess on my part? The time frame definitely would fit?
Thanks, Gary in N.Y.
P.S.
Casey, get the right parts and call it a day! Those lifters I showed in my earlier post are the very SAME ones in my good friend's ride (again, in my signature), he has the very same cam you mention (Isky's 88), it has about 40,000 miles it now?, and at the time the unit was FULLY assembled here in about a total of 4 or 5 hours! Not a single "snag" along the way, not one. That ride weighs close to 4000# (maybe more) and "pulls like freight-train", this was my friend's description when the unit was new and just installed.
