Use stock rockers and do the bearing upgrade from BTR. I had those same rockers and took the car to a shop for some upgrades and the first thing they did was took them of
and put factory ones back in. Maybe not all the problem but some of it.

Well they are made by PAC so you are on the right path....

Again, it's better to have the SYSTEM matched by a Valvetrain engineer.... Wish I knew one.

Excuse me because I haven't had coffee yet..... But when you ask a "expert" and he gets it wrong, especially knowing everything about the setup.... You aren't dealing with a competent person.

Tooley is w salesman, not a engineer. There is a reason I have to fix screw ups like this all the time.

This is a easy setup to make work.... The parts are light, the RPM is low, and it's normal streetcar lift. This isint a 8,000rpm+ stock Elminator motor or a 9,000rpm .700"+ lift flat tappet dirt motor that needs to go seasons on springs.

The geometry on the TFS heads are not my favorite (again another marvel of "experts") but they can be fixed to work....

Good Luck, I hope you find some better advice.

Was that rocker that's twisted, the bolt loose? Almost has to be.

I have seen cars with valve float issues put stock rockers back on, fix the valve float and pick up .5 at the dragstrip. Seen this numerous times.
Was tight as supposed to be.
