March performance vs cvf pulleys on 340

I almost thought i couldnt use the 6-1/2 crank/water pump set from march as i thought i may have a fluid damper, dug a little more and after looking at mine and finding mine on summit it is not a fluid damper. So that kit should work for me, i did notice that my water pump pulley is in further than the groove on the crank, not much but maybe 1/16”. With the outer groove on the crank 7” in diameter the water pump pulley couldnt come forward much as it would interfere with the outer groove on the crank. So the 6-1/2 crank may free up some more room for the waterpump pulley to come out a little. I get paid wednesday so hopefully i can get the parts ordered. I think im going to buy them from summit, about $30 cheaper than from march.
