gotta take out the valve and look at the seat where the valve seats on. you should be able to look at the angles you have.

Re: H22 3 angle valve job?? (H-EK22)
a 3 angle valve job is considerd to be a "standard valve job" and is what most people get when they have a valve job done. It's where the valve touches/sits on its seat in the head that these angles are. They are cut into the valve to allow it to seal properly in the head. Different head porters use different angles to enhance air flow so not all "valve jobs" are considered equal if it's not a standard spec (stock) valve job. A 5 angle valve job means it has 5 different angles cut instead of three. A 3 angle done right is all most people ever need.

Oh ok thanks for answereing my question....so with aftermarket valves like Ferrea did they have to get the valve job done and if not should i go an have it done at the shop...like is it worth doing it???

Anytime you replace valves with new ones or have your head ported, a valve job is mandatory.

I would beg to differ. Every head is different. It depends on so many things that you can't make a blanket statement like that. It may not need a full valve job but they most definalty need to be lapped in.

In the old days of just using stones, and the old valve seat material, lapping was a necessary. But with todays tech, those old rules just dont apply anymore. Are you hurting anything by lapping? No. Is it absolutely necessary with every VJ as stated by kpoweredhatch? No.

</TD></TR></TABLE>Yes,I can make that blanket statment,because it's true.
Explain to me how one head to another head affects the valve job.The valve job has no idea what head it's on,it's a machined surface.
Thats like saying everytime you change the head gasket you need to have the head and block surfaced.
If the valve job is concentric,the valve is also concentric/ground at the same angle,and the right size it will work.

I'll clarify what I was getting at. If you're changing old valves for new ones, you should do a valve job to clean the seats up so the new valves will seat properly. A head with any amount of mileage and high RPM abuse on it will deform the seats over time.
Often times when a head is ported, it's not out of the question that the grinder could knick a valve seat or two which would require a valve job to allow the valve to re-seal itself. Also any decent porting job that I've ever seen always has a valve job done afterwards since that's where the most gains are often found.

IF the valve job is in good shape I can take a good valve from any other seat or other head and replace them w/o any trouble.Such as replacing the valves from seat 8 to seat 1 if they are all concentric they don't know what seat they are on.
