I have a 261 in my truck, 270 cam grind, solid lifters, headers, 500 cfm holley, and flat top 60 over pistons. I have a extra 848 head that I would like to some porting on, and then have it angle milled around 160 thou., to 0, to help build comp. Does any one have any experience in doing this. I have heard it before some where, don't remember where though.
