ok my fellow flathead freaks ........
 

can one of you tell me if the isky and speedway adjustable lifters are hollow or solid ????? gonna order some parts me hopes soon and they are on the list . kinda leaning towards the flatattack hollow ones red's carries but still weighing the options . also any of you guys tell me does the factory 8cm cam got a lope to it or smooth idle ?? either way it's going in but kinda curious ........:):):):)

AFAIK the only ones that are hollow are the Flatattack ones, and some of the old Johnsons.

If you are using the 8CM cam, why use adjustables? Henry's production lifters are the lightest of all of them, extremely durable, and no worries about going out of adjustment for tens of thousands of miles. If your engine is apart, it's not "that" much more work to get the proper clearances with stock lifters. Adjustables are needed on reground cams and some hi-lift new cams, but an 8CM is a stock cam.

no access to a valve grinder ross . and i'm about as proficient as a cub bearing playing with itself with boxing gloves on with finite things like that . i know the oe ones are the best but due to circumstances i was onto plan b ...................

oh and outside of dave brown i dont trust anyone around here with a machine shop . i've seen some of the " fine " work they do . dave is fighting cancer so it may be tomorrow they're done or 6 months from now after i give him the measurements and the new valves .{ bud had a valve grinder but it's kinda broken now thanks to one of his grand kids playing with it }

The 8CM cam is a smooth idle.
