Piston to deck clearance 360

Does anybody know what the stock piston to deck clearance was on a 1989 360?

I am working on compression ratio and can't find the distance anywhere.

Also, are there any good head gaskets that keep the bore to a minimum and thickness as well to help compression? My engine is bored .030 over.

Thanks!

Not sure if the '89 360 roller engines were TBI or not, but the '89 318 TBI Roller engines are 9.2:1 cr with the pistons .040 down in the hole. Pic below.

Here is the thin 318 Mr. Gasket 1121G head gasket on a 360, plenty of room to seal there yet.
