You mean install the block guard THEN bore/hone. If properly tuned, a GSR sleeve will take just about all the high compression NA you would want. A bore/hone is the -proper- way to go about it, so dont skimp out on that either.
A very common overlooked part is a damper. If you're going to go with Eagle rods (most do unfortunately), their consistancy on the big bore leave little to be desired. Either way, reduce your crankshaft harmonics with the use of a damper, either ATI or Fluidampr, I prefer Fluidampr (fluid) vice ATI (rubber bands) personally. Though they both have their advantages/disadvantages just like any choice of options.
