thanks for ideas

i have change all o-rings before there is no need to make any changes but only one thing that i haven’t check real close which is the valve i’m going to replace it these days and check if there will be any changes i’ll post here

Measure the valve spring length and post.

Make sure not to install the pre-charge camber backwards, it will make the valve spring tension very hard and cause low velocities.
