Best valve angle's to cut?
Well I have been doing some thinking on the angle's I would like to use on my valve job's..These head's are 94 Aluminum LT1's with 2.00/1.56 Manley Raceflow's ..I don't know how LT1's and LS1's respond to different throat cut's and seat angle's..the race flow's are already back cut 30* on intake & exhaust..Let me know what you guy's think about these angle's I chose and if there are better angle's that you have had better luck with...INTAKE SEAT:60* throat cut,45* seat face,15* Top angle,..INTAKE VALVE:30* back cut,45* face with a .050 lower margin....EXHAUST SEAT:65* throat angle,45* seat face,30* Top cut....EXHAUST VALVE:30* back cut,45* face,.085 margin,25* radius...those are what I am thinking will produce the best flow number's..anyone had better luck with different angle's?..if so please share! thank's,
