Hand porting heads
Anyone ever try hand porting/polishing their cylinder heads? I realize that diamond cut CNC work is far superior, but it is also pretty costly. Back in the day I did some hand port/polish work on automotive heads but never on a HD. If you have done it I would be curious to hear your results. TIA

Unless you know what you are doing, you can actually reduce flow in your stock heads, The porting a Harley head is not the same as we did in the old days to our domestic V8s with gasket matching and porting to blend. Do not attempt unless you know what you are doing and or know somebody that has proven over time with flow bench numbers. There are gains to be had but only throught he hands of an expert, seek 1 out.
