I have my 325i head apart, port matching, grinding the valves etc.
I want to check the springs but I can't find the specifications in my Bentley Manual as to how many pounds they should be at a given height.
Help please?
Does it make sense to add a little washer under the springs to give them a little help during high rpms?
Thanks, Chuck
