Anthony,
Obviously the 80thou will give the lowest comp ratio. To work this out
properly you need to know bore, stoke, chamber volume and piston dish volume
etc. If you know this then its easy.

Subject: Lower Compression with copper headgasket?
This might be a tricky one...... let's see
I just got off the phone to ridgecrest.... they supply copper head gaskets
for FJ20T's and they told me they have them in 4 different thicknesses.
40thou $75
46thou $75
60thou $84
80thou $95
+GST
If my block is stoke and block are basically standard except it's gonna be
flat decked by the guy who's preparing it for me and my forged pistons are
20thou can anyobody guesstimate the best thickness to achieve a compression
ratio of about 7.6:1???
Thanks to whoever helps me with this one
Anthony
