"troft" thats the word I was looking for.
It has 4 valve reliefs with trofts connecting them into pairs.Probably 1 1/2 to 2cc's worth.
Hard telling without really measuring.
Might be the way for me to go,less I'll have to take out of the chamber to get where I need to be to run 87 octane.
Man, wouldn't it be nice to have the 240 back at the pump.
