hmm ive always just pulled the spark plugs and stuck my finger in the hole of #1 and turn the motor by hand till it just stops blowing air out (compression stroke) and timed from their. but im lazy.

ex-in-in-ex-ex-in-in-ex (intake and exhaust)



THanks..This is what i was trying to make sure.... BC I wanted to make sure i'm getting TDC off the comopression stroke, not the exhaust stroke..I did it correct, yay!!!

I'm not sure what you are getting at but the Y head has a valve arrangement of ex-in-in-ex-ex-in-in-ex (intake and exhaust) if you are looking for the compression stoke on #1 watch for overlap on #6 (exhaust valve almost closed and intake just opening, rockers just about even.)  Is this what you are asking?

Trying to get initial timing before breaking in the cam, I reached a dilemma. I'm not sure which is the compression and exhaust stroke... I took off the passenger side valve cover, and am on TDC. I'm confused because it looks like on the heads, the exhaust and intake valves alternate. Am I right? If I am, I have the timing down at 5 degrees, I know it should be at like 12, but I just want to get the came broken in.
