I had to put new head gaskets on it. I did my 89 it was easy, but it also has hydraulic lifters. Any help or web site info would be great.

Use the search function here to find "companion cylinder valve adjustment". The companion cylinders on a Chevy V8 are:
1 8 4 3
6 5 7 2
When #1 is "rocking", with the exhaust valve closing and the intake opening, #6 is on TDC of the compression stroke, ready to adjust. Follow the firing order, and all 16 valves can be adjusted in 2 turns of the engine.

Would have been built w/ hyd. If someone has changed cams w/ solid lifter type you would need to find the cam manufactures specs.
