You do not take the rocking in to account. Measure the height from the center of the piston directly above the pin.
as one side move up the other is going down so average is at the pin center line

how du you measure the distance above the deck?
With a deck height gauge that looks like this:

With the above tool you don't need a TDC finder, you zero the gauge to the deck once then measure each piston as it comes up to and past TDC.
Yes , a nice tool, no doubt.
I attach a pic of my home made stuff, not as nice as the professional tools, but it works.
Anyway, here are the new numbers:
Head gasket thickness inch 0,051 Cyl # $$ Max out inch $$$ Quench inches 1 0,006 0,045 2 0,006 0,045 3 0,008 0,043 4 0,007 0,044 5 0,008 0,043 6 0,006 0,045 7 0,008 0,043 8 0,009 0,042
I think that's as good as it gets, and personally I think it's good enough, and I will run it this way unless anybody has some compelling reason not to...
Oh well, the formatting looked good when I posted it...but it's not the best possible when displayed here...

I use a depth mike, you can use your tool with the dial indicator, some people use a dial caliper, some use feeler gauges like you did. Lots of ways to get results, I like to use a very thin flat screw driver blade to wedge between the piston top and the cylinder bore to rock it and hold it while measuring it I do measure them all at the front and back of the bores above the pins at the edge of the piston and the cam and then the outside of the block side also. I now use the highest measurement for my piston to cylinder head clearances, .035 averaged made the pistons hit the head lightly when running, .042 didn't hit

I have always used the positive stop method. Most accurate IMO. BTW, you don't need fancy color anodized tools to get accurate readings. Much of my stuff is home brew.

Hahaha, a direct copy of my setup...same degreeing wheel, and 2 lifters welded together!!
Ya, but is your pointer a coat hanger or welding rod? Actually, the degree wheel is modified. Got tired of screwing around with the crank snout mounting problem, so I cut the center out, made an adapter with 3 set screws so I can rotate the outer ring without having to loosen the crank mounting bolt. Works great.
Now that's an excellent design not to have to loosen the crank bolt, which is annoying and can easily change the position of the crank!!! I will remember that idea! My pointer is, as you can see, a multipurpose piece of soft iron wire... Here is what my engine looked like yesterday...

Cometic made me some .098 thick gaskets for my turbo build. There not cheep but they can make you any size thickness up to that.
I just bought .120 thick gaskets from them.

That's not a gasket, that's a torque plate !!!

Yeah I know. It wasn't the ideal thing but to make everything work with my heads and cam that's what I had to do. It still has 12.1:1 compression.

I've started working on the valve train, and checked the clearance between valves/pistons/heads... Using modelling clay, the quench was as calculated. What was a slight surprise though was the huge clearance between valves and piston. I don't have the exact numbers here right now, but you can see the thick layer of modelling clay in between. The cam is a Lunati 10230703 hydraulic installed straight up. Seems I have a lot of room for future maneuvering with cams... Forgot to say that the roller rockers are 1.6 ...
