I use the Cometic 91mm gasket.  I've purposely NOT taken more out of the 
intake pocket since it already goes way outside the bounds of the liner 
- I just took the sharp edges off to keep from getting a hot spot.

The Cometic does intrude into the combustion chamber next to the intake 
valve but not by very much.

I also make sure to not relieve the liner outside the bounds of the fire 
ring in the gasket so it's supported on at least one side and can pass 
the heat to the liner.  I don't blow head gaskets, but I also don't run 
one for more than 2 seasons, normally for just one season.

Regards, Tony

Joe, my experience is only with a hot street engine but worth =
expressing. 87mm pistons and liners, .090 milled from head and Kastner D =
cam.
I ran a stock AE330 for almost 40 years with no issues then I did a =
valve job and hardened EX seats because of recession in #4 EX valve =
seat. The shop took another approx. .010 off the head (so now approx. =
.100 off the head) . I used the Cometic 91mm gasket and it burned =
through at #4 in 2 years of street driving. Maybe 15,000 miles.
The engine was tired by this time having been rebuilt in the =
80=E2=80=99s. I rebuilt the engine and decided to use another AE330 with =
a new head at .070 milled. That gasket leaked because of my dumb mistake =
not re-torqueing after a few heat cycles. Replaced with another AE330 =
and now have approx. 10,000 miles with no issues. I did re-torque a =
couple of times.

Original AE330 copper gaskets are getting hard to find but occasionally =
show up on EBay, I just bought one. The =E2=80=9Cnew=E2=80=9D repro AE =
330 copper gaskets are not the same especially in the valve pocket area, =
I=E2=80=99ve compared them.

My point in al of this is take a look at how an original AE330 fits to =
your head and block and give it consideration, you might find it =
acceptable. Or continue to use the steel with thin copper wire that =
you=E2=80=99ve used. I am not a fan of the Cometic but admittedly mine =
was used on a street engine with no plans to change it every year. =
Tony=E2=80=99s experience is worthy of attention, he hammers that engine =

Cometic will do a custom gasket for a minimal one time charge. I've had a
Spitfire gasket made thick to make up for an over zealous block milling and
another one with a wider piston opening. Once they make the design changes,
they send you a PDF with the dimensions listed for your approval. When it's
OK, they assign a part number and CNC it out. Design turn around is about a
week and another week to make it. After the first one is made, just call up
and order replacements with your customer number, no extra charges.
