I'm installing 1.5 rockers on my 350 TPI, but which are the intake and exhaust valves? I don't know which is which or how it starts out. All I know is which ones to do on TDC and then rotate it 360 and finish off the rest? Thanks, Jason

Look at the 2 manifolds. See the runners? The valve that the intake runner points at is the intake, and the valve that the exhaust runner points at is the exhaust.

Pattern on the heads is EIIEEIIE

Thanks.

 

easiest way i know how is this:

from the front of the engine working towards the back make a rhyme:

"exhaust intake, intake exhaust.. exhaust intakek, intake exhaust"

 

Look at where your exhaust ports are, or where the manifold (or header) comes out, thats the exhaust valve, the other is of course the intake.
