Valve Jobs

[CamryCivicMan68]

Iam not a honda guy, i know alot more about toyotas. But, how much hp and what advantages come from getting a 3 angle or 5 angle valve?

I also heard that there are 7 angle valve jobs, how do they manage to be able to do seven angles?

Hondas are 3 angle from the factory. I think that a lot of shops claim more angles just as bragging rights. I would want to see some flowbench results to know if the valve job was worth anything. One advantage of a valvejob is just to ensure a good seat between the valve and valve seat.

i was looking at a 93 civic for sale a while ago that had an h22a engine, skunk2
camshafts and cam gears, and it had a 5 angle valve job

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.
