Valve Job

When people say they have a three angle valve job on their head or possibly another numerical figure angle job, what does this mean?

Re: Valve Job

Not to sure but i think that it means when u grind the valve seats for better air flow let me google and see what happens.

What i found out from good read to http://www.eddiesvalvegrinding.com/valve-grinding.htm
The Multi Angle Valve Job To Increase Head Flow and Performance

Our modified engines feature a multi angle valve job for increased head flow and performance. This usually entails placing different angles on the valve seat itself, increasing the flow of combustion gases and improving horsepower and torque. A multi angle valve job is the cutting or grinding of 2 or more angles on the seat and valve.

you lazy bastard!!! LOL

GOOGLE SEARCH
PRELUDE angle valve job
took 1.3 seconds

http://www.preludeonline.com/f93/3-a...illing-213950/

click this link and scroll down to "valve jobs"
http://books.google.com/books?id=2YA...esult#PPA48,M1


(′aŋˇgəl ′valv)

(design engineering) A manually operated valve with its outlet opening oriented at right angles to its inlet opening; used for regulating the flow of a fluid in a pipe

Hondas are 3 angle from the factory.

Multi-angle valve seats(and valves even) usually pick up some CFM over a single angle seat. They vary from head-to-head and port-to-port, however.

I'll be honest even after reading all that it's still a lil confusing... good luck Matthew

Re: Valve Job

GOD u newb u nee to use google
CFM-Cubic feet per minute
The cubic foot per minute (CFM) or actual cubic foot per minute (ACFM) is a unit of volumetric capacity commonly used by manufacturers of blowers and compressors. Since the volumetric capacity refers to the volume of air or other gas at the inlet to the unit, it is also often referred to as Inlet CFM (ICFM). All three terms (CFM, ACFM or ICFM) are used interchangeably to mean basically the same thing.

So it means air flow the better the engine can get and get ride of the "air" the better
