does not matter.
The shop would have put left and right on the head when they were resurfaced if it mattered.

 

kinda what I was thinking, appreciate it
have a good weekend, I will be in the garage.................

 

I did the front cover, timing chain, water pump this past fall. Just take your time. use gasket remover to get a nice clean surface for the timing cover gasket. I used that Permatex gasket helper. It looks like red translucent rubber cement. It basically holds the oddy shaped timing gasket to the cover...mean while you can concentrate on lining up all the correct guide posts and get your bolts started.
Timing chain is not hard. follow the RAVE on the triangle shape tick marks on the gears to get it lined up correctly. Not difficult but triple check your work, before you put the cover back on.

I have not done the heads yet. I'm at 115,000 so far & fingers crossed
