Hi people. So, my SR is getting a bit further with the rebuild. Head is all skimmed, valves reseated, BC springs and retainers, new BC guides. Black has been decked, put together with Manley rods and CP (8.5) pistons and bored out to 86.5mm with all new Duraglide shells and I also had my crank + damper + flywheel + clutch cover balanced. Once the head has been skimmed and the block has been decked, in total, 0.25mm has been taken off. When the engine was stripped, turned out the head has never been skimmed in its life and was on the original HG after we measured the head height. I'm about to hit 'buy' on a head gasket but in two minds what size to get. Strictly speaking a 1.5mm is the next logical choice but its a bit much and one or two people suggested going with a 1.2mm as the clearance should be fine. Could anyone else please help as there are still SR20 guru's on this forum.
