My home inspection of Speedmaster heads

Just the xmas present I wanted, flow numbers.

Without getting too far off topic, that's a fancy case. Do you run a glide because of the sfi case or...?



I’ve been running glides since around 1990 or so. I switched to aftermarket cases three years ago after I cracked a stock case behind the reverse low gear clutch pack oiling the track. I hate being “that guy”.
