The springs installed into the Trick Flow heads without any issues. The spring locator drops right in place without any machine work. Installed height in my heads was 1.975 and the seat pressure was 205 lbs. Open pressure at 0.750 lift is 660 lbs.

The conical spring is smaller at the top so there is a ton of clearance around the rocker arm. I had clearance issues with the T&D rocker arms with the dual springs that were in there but now there is plenty of space.

I also test fitted some 7/16 dual taper pushrods. They almost fit but rubbed a little bit so we'll pull the heads and do a little machine work. Should have the engine back on the dyno around the end of the month.
