You will be also wanting the squish angle and length of squish cut re done also, also you need to tell who does this the bore size, seen prices from low as $60 to $200 depending on who you use

Mitch in order to have these two things done (squish and o ring) you have to send your entire engine or just your head?

You can just do the head, best way is to have the engine there to make sure of clearances and the squish gap is set correctly (0.050" to .055").

My answer to that is yes.

To get the squish right, the builder needs to verify the cylinder height. There may have been previous milling to the cylinder base or top.

Does coolant seep thru the nuts/head studs? What's the way to handle it?

If yoru using a cool dome then you would be using the 88 head studs (10mm base - 8 mm top) I use an o ring on the step then use copper washers with non serrated (flat) nuts, its hard to get tall enough acorn nuts (sealed top nuts)
its the same for 10mm studs (minus the O rings on the studs)

I've been doing the orings for 3+ years. Not sure where 414 got his information from.
