Found some cometic instructions that say remove the brass rivet if it fouls (it did) its only brass so pish easy.
Measured the cc in the block, 11cc so i can work out the cr if i get a figure somewhere for the cometic..

1cc for the gasket seems low most have a volume of 3 to 4cc when compressed. If the CR is too high and you have no where else, so to speak, to create a bigger compressed volume ie piston then last resort is to re-centre the rods ( shorter ) or have a bespoke set made to suit.

12.4 might be OK with a 300 degree cam.
