cam degreeing kit?

the weiand intake is a dualplane, it has tall runners i'll get the #'s off it. the energizer specs. are 216-216-454-454 the comps not that much bigger,and i thought the dualpattern would help, i'm trying to buy a ld340 intake now but if i don't get it i'll be putting the 340 back on, i'm gasket matching porting it now, it was pretty close
