22RE cylinder head valve seat install and valve seat cutting

[andrealberto12]

@putneyscustommachine i had a question.. my engine oil has foam what can i do????????

How do you perfectly align the angle and position of the cutting head with the ports themselves? Is it by inserting that long shaft at the end of the tool into the valve guides for example?

nice!! how much for a head like that??

does it come complete with valves?

[putneyscustommachine]

Check out our cylinder head page on our site (22reperformance(dot)com), for a better idea on pricing. That will have all of the specs and parts we use for a stock fuel system truck. If you are running a modified fuel system, let us know what it is and which manifold you plan on using. FULLY porting the head all the way from the intake to the valve (or the exhaust side) can actually LOSE you power in some cases, so it is not always recommended.

what about valve faces??

Everyone only shows the valve SEAT profile!.... what about the valve face!?

[putneyscustommachine]

Hey, that is a REALLLLLY good question! Like all of the others, we didn't explain it. It kind of slipped my mind since, to us, it's a no-brainer....

The profiles WE cut into the seats are based on the valve that we install. We have our valves custom made. The cutter we use and the profile we cut are measured off of the VALVE itself. The only part of the valve that contacts the seat is the 45 degree angle that is already cut into the valve when they are made for us.

is valve SEAT profile more important than valve FACE profile??

Can u radius the valve face??

[putneyscustommachine]

NO. The seat profile and the valve face profile have to work together to get the best flow.

The 45 degree angle of the seat and valve face are the only parts that have to mesh with each other to get the proper sealing.

We cut the radius in the seats to work optimal with the custom valve we have made (the valve face is convex and has the proper back cuts for optimal flow).

You can 'back-cut' a stock valve (cut the portion above the 45 degree cut) to help flow, but the stock valve has

@putneyscustommachine~ u say your valve face is convex..... so its radiused??

[putneyscustommachine]

too much of a concave face and too much of a lip to flow optimally.

That is why we have stainless valves made to our specs, it avoids the need for a back cut.

Stock valves can be made to flow much better, but at the cost of lesser longevity.

Sorry if I am vague, but it's hard to answer in a 500 character box.

You can call us for more details and we can bore you to death with the details. :)

[marek0086]

No way! I like tech talk..... it gets me off. XD

[putneyscustommachine]

You can see the side by side valve face (and ramp of the face) comparison on our site. Check the "cylinder head" page at 22reperformance(dot)com.

Good question, and thanks for pointing that part out.

[marek0086]

So when u have a radiused seat and face.... that means the contact area is tiny!

Wouldn't the face and seat "pound" each other flat after a while?.... because u have such high psi on the contact area due to a very small contact area surface?

[marek0086]

haha.... i cant call u.... im from Australia.

how much does it cost to get a 22re head completely ported and polished and to get the valve seats changed to better 1s?what are the best valves to use? thanks
