Default help with MLS head gasket for 1.6

for my current build im using a multi-layer steel gasket for better reliability then the OEM composite.

I found two different vendors that sell the MLS 1.6 gaskets but im a little confused one which to pick since i overbored by 1mm.

Here is the Cometic one offered by 'BE', It comes with the option for a different thickness but no overbore sizes ?
Boundary Engineering

And Flyin' Miata's gasket, no thickness options but has one that fits stock to 1mm overbored blocks
Flyin' Miata : Engine/Drivetrain : Internals : 1990-93 0.040" metal head gasket

And ebay! with another cometic gasket, says with works with the stock 78mm bore up to the 80mm bore (+2mm overbore)
Cometic MLS Head Gasket Mazda B6ZE NA MX-5 Miata 89-93 : eBay Motors (item 170456991777 end time Apr-08-10 17:34:59 PDT)

Just want to run this by with you guys to make sure im making the best choice for my build.

Thanks in advance!

I'm pretty sure that the OEM head gasket will accommodate a 1mm overbore, and I see no reason why a "stock-like" MLS gasket probably wouldn't either.

Don't increase the gasket thickness beyond stock.

All the cometic ones support an 80mm bore. I <3 cometic. I'm nearly 100% certain the FM one is also a cometic gasket as I know of no one else that makes a mls gasket for the b6.
