I'm planning on a 95" upgrade to my '06 Heritage and am now aware that this is the best time to look at updating the heads to match the increase in displacement. There are a couple of shops nearby that specialize in head porting which I have learned involves grinding, welding and polishing the ports to improve the flow of fuel in and exhaust out. Coming from a product design and manufacture background, I wonder if a better choice would be to go with a proven performance head design that is in production. Doing searches on the net, it appears that there are hundreds of shops that have ported thousands of heads. There are also production designs for performance heads on the market. Which is the better way to go and why? Thanks. :33:
