Is your builder responsible for that mixed and matched bastardized pushrod set?

And remember, its a w2, so the intake rocker pushes to one side as it gets on the lobe. When setting lash, you have to sorta hold/push it over while you set lash.

Also, Make sure your rocker shims are on the side of the intake rocker that gets the load from the pushrod angle. Or said another way- on both sides of the exhaust rocker its paired with. IMO a shim isnt necessary on the one side of the intake rocker that is opposite the offset adjuster.
