Diagnostic trouble codes (misfires & camshaft positions)
After rebuilding both heads and using the camlock tools, I figured that the hard part was completed. I was wrong. However, it started on the 2nd attempt after 2.5 mos of downtime. Here are my following codes:
1. P0300 - Random/multiple cylinder misfires
2. P0303 - Cyl #3 misfire
3. P0302 - Cyl #2 misfire
4. P0441 - Evap Emission Control System purge Flow Fault
5. P0341 - Camshaft Position Sensor A - Bank 1
6. P0366 - Camshaft position Sensor B - Bank 1
7. P0301 - Cyl #1 misfire
Sounds like my camshafts are off on the passenger head and a possible vacuum leak. Is it possible to be off 1 degree on the camshafts when using the camlock tools??
Any advice is greatly appreciated!

I beleive bank one is the drivers side not the passenger side and it sounds like there is definetly a timing problem. I would start by taking off the valve covers and lining up the crank and seeing where your timing marks are on the cams. you can get the timing off if you dont preload the timing belt as you put it on and make sure all the slack is on the tensioner side. the other issue could be the timing between the cams especially on the drivers side because of where the timing marks for the cam chain fall. if you look at the timing mark on the intake cam on the drivers side it falls on the center of a tooth not in the valley of a tooth as all the other cams do. when you counted the 16 teeth between marks did you line up the mark on the left or right side of that tooth if you were standing in front of the car looking at the cams? if you went to the left the timing will be off it must line up on the right side of the tooth for the timing to be correct even though the cam marks will line up ok with it on either side. Beleive me I learned this one the hard way!

TDC is off by 180 degrees???
I notice if i turn the crankshaft 360 degrees, my camshafts only turn 180 degrees. Since I know that #1 & #2 valves are open, how do I carefully avoid damaging the valves when I turn the crankshaft another 360 degrees to set the correct TDC???

Scratch the 360 degrees idea. . .
Before placing the camlocks, again, I marked my intake camshaft pulleys and timing belt at TDC. I realized at TDC, i could not place my camlock on the passenge side head but it went on the driver side head. At the end, the intake camshaft was off by 1 teeth. However, I noticed that my TDC mark on the crankshaft had moved slightly when I tightened the bearing roller and released the pin from the belt tensioner. The passenger intake camshaft pulley has a little more play than the driver side intake pulley.
Here are my new codes:
1. P0113 - IAT Sensor 1 Circuit
High Input
2. P0366 - Camshaft position Sensor B - BAnk 1
CKT Range Pert
3. P0300 - Multiple misfires
4. P0303 - cyl #3 misfires
5. P0102 - MAF or VAF A Circuit
Low Input
6. P0302 - cyl #2 misfires
