99-up PI heads
Hi all,
I am new to the forum world.
I have enjoyed reading many of your forums and found them very informative.
My Question, how important is the wall by the intake valve on 99-up PI heads.
I have read somewhere that it shrouds the valve.
Is there any improvement from removing it?
Any comment will be welcome.
Thanks,
ROB
