Interesting OEM 522 Whippled EFI engine build.

Left one cylinder head off until I had the timing cover and balancer. Need to use the piston stop tool to find exact TDC.
Found it. You might notice the engine changed color also.

The GM Gen VI timing cover has a pointer built on. The stock balancer is 8" and the new one is 7" . Will not work. Was worth a try.

Should not be a problem filling these cylinders. What looks like a step is a digital camera optical illusion. The black is the hard anodizing. The entire head casting was hard anodized before machining.

Thanks GM for providing this intake valley pan. It is a nice feature. Will keep the hot oil from splashing the bottom of the intake manifold. The intake will have an integrated intercooler as well. Every little bit helps.
