The trouble with sm bbm heads is the rpm copies are gone. The ones they have now are Victor copies, and use offset rockers.Black Friday sale at Speedmaster is right around the corner.... see what they have (I won't buy their BB heads)
They are a bunch bigger than tf's even. I think the cnc version are 320cc intake runner. (WAY too big fur a 7.4 motor, lol).
