Seems like that would be a subject for a new thread.

Are those T&D rockers, or PRW?

T&D

That has to be at least 0.150" increase spring height with the retainer/lock combination for the valve stem to be so close to the top of the retainer.
Both sets of MW Victors, we milled off the rocker stands and used the billet aluminum max wedge type stands so we could control the stand height.
Also used lash caps to increase the rocker to retainer clearance. The valve spring locators we used are only 0.030" thick compared to the standard 0.060" thickness.
It looks like 0.030" was just taken off the bottom of 0.060" locators. PAC provided the 1326 springs, Locators, and retainers for the current set of Hughes CNC ported MW Victors. The old set of heads used PAC 1325 springs and Crower +0.100" retainers with the normal 0.060" spring locators, but the spring pockets were cut a bit deeper. I don't recommend making the spring pockets deeper or you can break through into the Intake port roof.

What's not perfect about it?

The roller pattern is not centered on the stem. I guess i got lucky here seeing so many having trouble with this. HS will drill the rockers for pushrod oiling if ya like fee of charge.

Hey Jim,
You make great power with everything you do, but even though you did it without things being perfect in the past, I suspect you wouldn't do it again without making sure it was right. You and I both know why the posted pic isn't perfect, but I wanted to see if the poster knew why it wasn't perfect. Anecdotal evidence isn't a good reason to encourage someone to do the wrong thing. Just trying to make it an educational moment, without beating anybody up, figuratively speaking.

Sometimes I feel like "anecdotal evidence" and 'Glory Days' is all I'm running on now.


Yet you are correct, I will make many corrections on the things I do in the future. I might even shorten that sweep up to about 1/3-1/4 of what it is now.

Contrary to popular belief, and much of the information out there, a centered pattern is not good geometry on a roller rocker. That information was originally put out for factory engineered ductile iron rockers, and has been been applied to roller rockers, which is incorrect.

Sounds like an awful lot of work. If you milled the stands off anyway, why not just put a longer valve in the head to get the installed height and forego the lash caps, +.100" retainers, and cut down spring seats or spring pockets?

In hind sight that would be the way to go. Was using the valves that came with the heads.
On the first set of heads, early production version (short maybe 1/2" long heli-coils in the stands, not going into the head area) the rocker stands cracked and broke, so the milling of the stands was more of a repair option. After milling the stands, 3/4" long solid stainless Time Serts were installed into the head where the stands were, and long ARP studs were used to fold the rocker shaft system with the WM Blocks to the head.
On the newer heads, I was waiting for the shorter ARP studs, and used used "Grade 8"? studs at the center and end holdowns. Those supposed grade 8 stud broke on one end of the rocker shaft, and snapper the shaft in half, while putting a hole in the valve cover.
With over 700+# open valve spring pressure, the hold downs become critical. When I first started using the Victor heads, there was no paired shaft rocker arm system, but T&D now sells one. Likely a better way to go when running over 0.700" lift.
