Need to finish talking them apart, do my dimensional checks first, but then I'll clean up there little bit that needs it before they go off for flow and valve job.
A side note here, I'm still ahead of the game vs trick flows, but for anyone who doesn't plan to run them out of the box, the deal is much closer than the sale price would indicate.
Shipping both ways to PRH, valve job, valve seals, and the b3 kit, all of which should be unneeded with the TF heads, all of it adds up.
