Head gasket
I have a 2005 88” that I’m having bored to a 95, I’m using wiseco forged 9.5 to 1 tracker pistons with the fueling 543 cams. My heads are being milled slightly to smooth out the mating surface. What thickness gasket should I use to get 10 to 1 compression or slightly higher without compression releases.

To make 10:1 you need to do the following.
Set the pistons to a zero deck height in the cylinders
Use a 0.030" head gasket
Have the head gasket surface milled until you have a 78cc combustion chamber
Added: This is assuming these pistons are flat top.

The most common size I see is .030, from Harley and cometic. James makes a .35, but since you want to 10, I am guess you want .03. Email cometic or one of the other companies you are working with
Funny how .030 has become common. I believe stock is .043 or .045. Going thinner was seen as crazy by some back then.

A tighter squish is beneficial. .030 to .035 is ideal. Some have done and they sell a .027.
