I don't have flow bench, but these heads are not meant to end up as racing heads, they should just be as close as you can get by comparing them optically and measurably.
does any one have any picturs of what a porting job should look like? Or what they have ported themselves and has proved good? I've used the search function, but if you type in "porting" you get about a million results, but I found no photos :(
Thanks for any help, I really appreciate it!
