The old and the new...
There is enough clearance in the bolt holes for things to move around a little so to make sure the rockers are in the exact right location, I drilled and pinned the stands with 1/8" roll pins, on on each end.
This is after the changes were made to the intake rocker stand. Checking sweep and geometry, this is the final result. The original stand was perfect for height (geometry), just needed to get the rocker closer to the valve
Here's the sweep with the new exhaust rocker strands. That's as good as it gets.
Some things weren't obvious till the changes were made like the location of the bolt hole and slot that bolts the rockers together. I'll have to move that over about .050". Other than that, this was a big home run for these heads.
Here's the rest of the project;
