I just got the figures back from Dwayne on my BB Speedmasters. He had to clean up the valve job, adjust guide clearances, and mill them (because I ordered 75cc heads and of course they were delivered with the 84cc chambers, which I didn't discover for months). Then the basic Stage 1 port job (bowl work and cleanup), also trimming the guides and blending them into the bowl.

I like it... nice improvement across the board.
It wouldn't have been worth going to Stage 2 full porting on these heads for my build. For higher hp, start with a $2000 pair of TF240's and go up from there wink
