speedmaster 2.02 valve heads on a 318

Just pulled up pix on the net. Pass side is the same. Drivers side front mount ear isvin same location as the 318. the issue is the AFT mount ear is closer to the front mount ear by 1/4"

I am gonna assume correctly that my 1/4" shim spacer will have to be reused on the front ear of the 360, as it looks to be in the same location on the block as my 318 and the afore mentioned alignment issues. Looks like the rear part of the spool mount bracket on the drivers side will need to be cut and moved forward.
