Ok I got some supposed "track heat" heads off of ebay and I was looking at them and they dont say trickflow anywhere. These are 3/8" rocker arm to head studs also. I look at the heads and they look like trickflow from the back and have the SN XXXX on the center of the exhaust side of the head too. The only thing that doesnt match up modern trickflows is the area where the rocker arm studs go in. These have a sort of diagonal area that you can see in the pics.

I also looked at practically every other ford head manufacturer and none other are close.

Weird thing is though that front of the heads say engraved R.A.P. , then about 2 inches lower also engraved T.S.M.

These heads are ported pretty damn good too and the only thing I can think that is going on is R.A.P. is Ron Anderson Performance (ron anderson was a pretty damn good porter) and these are the older model trickflow heads that he ported.

No idea what TSM is though ? Summit racing had no idea either. Ill call trickflow tomorrow to see if they ever made their rocker stud area with a diagonal design.

Dont know , but isnt trick flow the only head manufacturer that moves there valves like that ? Either way , they look good

Well first off these are the old trickflow heads that have pedestal mount. So now I need to get rid of all this shaft mount crap and send back the all the shaft mount parts. Oh well atleast the pushrods are the right length. Hopefully Ill have her running tomorrow night.

Trickflow had no idea what the RAP TSM part was though but the diagonal V type area is the old pedestal mount 5/16 design that takes the stock E7 type pedestal bolts.
