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.

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.

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.

Wrong </TD></TR></TABLE> Please explain why

Combustion Contraption

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.

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.

Good stuff guys............But whos right?????

H-EK22

so i guess ill post some pics up an you guys can tell me if it had a valve job done, or ill just take it to the shop and have them tell me if i need it or not, THANKS.......................also do those valves look in good shape or need better pic thank H-T

Fkned

Couldn't tell you that from pics

Combustion Contraption

How can we tell if you have a VJ by looking at pics taken from 3 feet away with the valves installed and with what looks to be a cell phone camera?

wed3k

there we go...



the three angles should be easily made out

Fkned

You can tell the exh has had a fresh valve job ,but I can't see the int well enough.But I'd think it would also.Who does half a vj?

Stock H22 with street valve job ... only thing changed was some Ferrea OEM sized valves

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.

Thaanks alot guys, all this info is really helping me out!!!!

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.
