Who are you using for a builder in this area?

Not a builder in the strick sense. A harley mechanic who does work on the side. Not sure he'd want me to put his name out here on the forum.

My money says that he never even checked the deck hight and just assembled the parts for you.
The average HD Dealership will do the same. The customers don't notice and they get paid the same.

It's these little details that put your build in front of the average build.
One step closer to perfection.

This is correct. And... things like this are so easy to check. There is an 'average' build... a good build... and a sucky build... even when the three builds use the exact same components. The more 'small stuff', that dealers generally blow off, one optimizes the better. One cannot get everything perfect, but things balance out in the total build.

A good squish of 030 to 040 helps turbulence in the combustion chambers for a more complete burn. The better burn makes the bike easier to tune. AN easier to tune bike will maybe have a noticeable difference in how it rides and reacts to throttle inputs. Stock bike can have squish of 060 or better... enough where there is really no squish to aid combustion much.

My deck height with the S&S cylinders were .003 proud. I ran a 040 gasket.... I have a bagger and felt that carbon, etc would be an issue with a squish less than 030.

You can order .021 copper head gaskets right off the Big Boyz website

Dropped my heads off a Big Boyz yesterday. Had a good talk with Bean. Now I just wait for Spring.

Bean is an encyclopedia of knowledge............love hanging out and talking with him. I would also recommend bringing your bike up to Bean in the spring and let him dyno tune it for you, he'll do the best job of anyone. Steve

So you have the answer to your question now because with the heads off it is easy to measure the deck height.

I am very interested in hearing what he finds his deck hight to be.

Don't leave us hangin' dude! You have no choice but to measure now (or look like a fool if you don't). He he!
