Hello all! I have questions about a build I'm doing on my banshee. I just got it last year, and melted a piston recently due to a leaky head gasket that caused a over-heat cyl to piston weld problem. Digging into it, I found out it came with a 4mil short rod stroker with a spacer under the cylinders. I want to delete the spacer and bought a cool head. I'm going to turn the domes to accept the 2mm pop-up, then redo the chambers to get the right cc. But that's getting ahead of myself because that'll happen after the cyls are finally on to get a deckheight measurement for the correct squish with the stock 0.20 base gaskets. THE PROBLEM: I ordered stage III porting templates from Race Logic, and am trying to figure out how to line them up. Do I go off the top of the cylinder, or do I compensate for the raised piston height? And then at that rate, do I raise the transfers as well? After many searches that had conflicting info, I'm not familiar with the right timing numbers for this type of build, but I do have a degree wheel and have no problem mapping it out. The templates sounded like the easy way to siamese the porting. Thanks in advance!
