what are the pro and cons of a 3 angle valve job. ive got some that are bent and i figured that if i was replacing the valves why not do a 3 angle job. but im not sure what that would gain, if anything. someone dshed a little light for me. thanks

3 angle valve jobs are stock. 5 angles can flow better, but are not necessary for stock-ish power levels.

 

if im running skunk stg 2 cams, and 12.5:1 ratio, would it be beneficial?

 

You may also want to research the specific angles that get the job done as well as seat width and back cutting the angles on the valves. I ain't an expert on this, but I know it isn't just the number of angles that are cut.

At the risk of starting a new fire fight, you might want to check the Endyne website. There used to be info on this topic.

im not actually going to do the work myself, i just wanted to know if the mod was worth the money. if it will increase my power, or if its trivial

 

Trivial, unless you have someone familiar with building honda race engines doing the work for you. Alot of the information comes out of trial and error. Three angle is stock too.

 

simply put, the better the valve job, the better flow you will have at low cam lift.

Pretty much.

The factory casting creates a lip that can be taken away to increase flow, not sure if that would be considered an added angle, but that is the only 'flaw' in the chamber design.
