Long story short. All exhaust valves got bent while cranking after timing chain stretched too much. I just got the head back with all new valves. It starts fine and runs, but with the rough idle and miss on #1. Good spark, injector is good, compression matched the other cylinders. It's only missing under 1000 rpm. I didn't adjust the valves when I put it back together. Is that the next place to start? I've checked vacuum lines as well and didn't find any issue. And if valve adjustment is the fix. What are the specs for the cap on intake and exhaust?

Thanks in advance!

DEFINITELY check your valve clearances...should have done that as part of the cylinder head replacement! Clearance specs should be on a sticker, on the hood.


How do you know your spark is good? Could be a bad coil...swap and see if the misfire moves.

How old are plugs? Are they the proper NGK or Denso iridiums?
