Hey Don,I am doin a 107 this winter been lookin to do a little more head work,I'm going to run a Andrews 54h with 10.25:1 CP pistons.I currently have the SE factory cnc ported heads from what info I can get on them they have a 1.875 intake and 1.575 Ex. and cc at 85cc.I was thinkin a bigger intake 1.9 and leavin the Ex.valve the same,also want the singh grooves, if they do cc at 85 tthat would put me at about 199 ccp at about 10;5.1.If I go 87cc that what put me at about 194ccp 10:25.1. Didnt know if they'd benefit from a little more port work or not was thinkin of sendin them your way but didn't know what it might cost me hate to say this but tryin to keep the budget down on this.Also your opinion on what I had in mind.
