J,

I'm going to go the W-9 rout but I'm saving my penny's to buy the R3 with a 9.600" deck 48* block.

I was told that you could buy the 59* W-9 and they will work on a 48* block. The 59* W-9 has all the work already done to them but they will only have 4 bolts not six because they cut the front of the head as well as the valley side.

More good news, I have a complete Predator top end and a KB block. 596 coming very soon.

I might even get the Duster out a couple times this year with the motor you dynoed.
