Tomei valve seat pressure?

[jdmser]

Anybody happen to know the standard valve seat pressure for Tomie's rb20 valve springs?

Found it. Install height is 35mm, seat pressure is 24kg or 53lbs, and lift load is 80.6kg or 177.3lbs.

We also just cc'd the head to 42cc. This was on a head that has had couple of valve jobs. One seems to have cut the seats a little low so on a good head it would end up around 41cc.
