3 angle valve job Vs. multi angle valve job

I was wondering the difference between the two IN PERFORMANCE. My setup i'm shooting for is 220+ whp and 150+ wtq. Is there a big difference IN PERFORMANCE. between a 3 or 5 angle valve job?

Re: (sheepey)

At its most basic level....the more angles a valve job has the better the seating for the valve. More angles = less obstruction for the fuel/air charge when it enters the head also. I'm sure one of the guru's can go into greater detail.

Re: 3 angle valve job Vs. multi angle valve job (kidd_drastic)

The correct answer is: there is no correct answer. Different porters get different results with different valve jobs. One kind is not universally better with every port.

Stick with 3 and stock valves.

Re: 3 angle valve job Vs. multi angle valve job (kidd_drastic)

Basics:
Radius > angle.
Stock valve job = stock flow, for the most part.

Re: (xEnderx)

wouldn't something like a mira-cut (5 angle) job help increase the overall flow out of the port since there are more angles? The increase in angles supposedly allows a more gradual transition from the port to the combustion chamber while still allowing the valves to seat. The same goes for the angles on the valve, though i think most folks stick to 3 angles on the valve.
I don't do much head work, so I'm not really sure. Any insight?

as stated before, a full-radius valve job done on a Serdi machine is best

a full radius valve job? isn't that both 3 and 5 angle.

Re: 3 angle valve job Vs. multi angle valve job (kidd_drastic)

In theory should help but no enough to see huge gains in reality. 3 angle and some slight oversized valves. All my heads get a 3 angle valve job.
