The MOST important thing with a sf-110 is all the corrections. You HAVE to do temp & barometric pressure corrections to get accurate cfm numbers.





barometric corrections on an SF-110???
no mention of that in my owners manual....and based on the operating prinicple of the machine, i dont know why the barometric pressure would have any affect on the readings.

as for the valve job deal.....i'm pretty "bread and butter" in that dept, and i re-do the valve seats more to make sure they are concentric than for any big gains in flow.
i usually do a std 3 angle on the intakes, along with a bowl cut, which gets blended into the bowl.
the exhaust usually gets a two angle/radiused bottom cut.....pretty much like what comes on most aftermerket heads these days.
