Default Help ID TrickFlow heads please

Picked these up here locally in the PNW a while back. Trying to see if anyone recognized them or the markings.
They are TrickFlow and have a casting number of 9210 on the usual spot. They are then engraved with 225 CNC.
On the front of the heads I have J03414 and 4802 stamped.
I know it is a shot in the dark, but figured I would ask

Yes sir. Emailed them yesterday.
The heads appear to have had some additional hand work done to them. (Smoothed out the usual CNC ridges)
so those other numbers may have come from elsewhere.

My guess would be Mamo or BTR if they've been touched up.
