Removed the valve springs from a head i bought and noticed these two seals on the exhaust side are not fully on so i tried pressing them on with a valve seal tool , but they wont go into place. Should i jus replace all valve seals ?

 

Look seated to me

 

Compared to the first pic

 

If you look closely you can see the seals on the first pic are not fully seated like how the ones in the second picture are

 

Maybe these two guides installation height differ little bit?

 

I'm not quite sure. I'd have to check the seals on the intake side. But this head do have the bronzeguides

 

If i remember correctly, arent exhaust seals brown? Intakes are blue? Or is this just with supertech?

 

Exhaust should be blue and intake brown.

 

Noticed, that's why I mentioned installation height. It's not imposible that couple guides are sitting little higher and then it looks like that seal isn't seated properly because you see part of guide between seal and valvespring seat.


Correct, Supertech seals should be just like that. Ferreas are both blue, intake and exhaust.

 

They look fine to me. if your trying to push them down, and they arent going any further, its because they are all the way down. like others have stated, its possible those two guides are slightly higher which is making it seem like its not seated properly.

 

Might be a good time to check the retainer to valve stem seal clearance. Especially when running larger cams.
It looks like one of those seals may already be contacting. Unless it's just marked from you pressing it.

 

 

All the seals have been removed now . I will be replacing the seals with brand new ones ...should I run the supertech ones again or will OEM be fine ? I'm working towards a ls/b20vtec . the cams I have are toda b's.

 

OEM is perfectly fine, get them and be done w it.
