Economical replacement rocker arm set?

There is also an HT2001R, which is an anti-pump-up version of the same lifter. Not sure which you have... probably the non-R version based on pix of ones with the wire clips. I don't know if the piston's cup height is exactly the same between the 2.

I saw that but it is special order. I haven't connected with Comp yet but for $12 my impatience tells me to get these two local and give it a go today. I don't think it is a lifter issue but it would be dumb not to try, just in case. Unless there is a large chance I will do damage to the cam on the break in cycle!?!

Here is why I don't think its a lifter issue. When I used the stethoscope the sound was the loudest on the rocker shaft, as if I had placed the scope right on the problem area. I was able to place the scope on the pushrod and the sound was weaker, however I did have to deal with it oscillating up and down.
