Cool S&S 113" push rod problem

The push rod is hitting the bottom of the top push rod tube. The front exhaust being the worst. I've tried trimming the bottom of the top tube but it still hits. I've tried spinning the tube to see if it will sit differently but still no good. Tried new S&S push rod tubes & their Quickee push rods, still hitting.
I'm running Jim's roller rockers, (stock geometry: 1.625:1) I'm wondering if going to a corrected geometry of 1.7:1 would help. I'm running the Woods W9F .650 lift cam with their valve springs & S&S hydraulic lifters with the HL2T Limited Travel Kit installed.
Anybody out there have any suggestions 'cuz I've just about run out of ideas?

If your 113" has S&S heads I would say it's the .650 lift cam causing the problem . If you have HD heads on it then the push rod tube holes have to be recut . There's a special cutting tool for doing just that .
I think the 1.7:1 rocker would increase the pushrod angle , not decrease it .

I use the smaller diameter Smith Bros pushrods. What size adjuster nuts do the S&S pushrods have? Delkron also makes some offset rocker stantions if the problem is the pushrods hitting the holes in the heads. I believe Bob Woods sells them.

Those are for T/C's, and are to be used with 7mm valves. The OP has an Evo.
