Just some simple questions i have been pondering...the basic "standard" 3 angle vj is 60/45/30 or thats what i have always used anyways ...but the throat cut of 60* vs a 75* throat would seem more beneficial...in some ways.my main question is how would a 75* throat stack up to a 60* with both having a 45* seat cut and 30* top cut?the 75* would enlarge the bowl by a firly large amount but make the transition into the seat more abrupt...general rule is throat should be 80% of the valve diameter or so.any thoughts on the 75* vs 60* throat...and has anyone experimented with changing the seat angle on the exhaust side to 50*-55* with a higher degree top and throat cut?Any info woud be great. Thank's,

Carter
