question .im putting a 318 together .i was wonderin if anyone knows if keith black 167 piston valve reliefs are symetrical.thank u
You are correct for me..... I checked your link.... same paper as came in the box with some KB pistons here. It shows the assymetrical orientation for 340 pistons, but it also says that some pistons have the same symmetrical valve reliefs and can go in any hole... The 340 KB pistons put in here were symmetrical, despite being listed in this paper as having assymetrical eyebrows, and the pix I linked shows the KB167 with symmetrical eyebrows, so that seemed to settle it. So you are saying your KB167's did not have symmetrical eyebrows?Be careful where you position each piston it matters.
I guess the others never build a 318 w/kb167's...
