Default Engine head shims ? Sirio / 30%

hey all,

as in title does anyone have a guide as what size shim should be run in a sirio evo3 for 30% byron Gen 2 fuel.

Even a base starting point would be good as I've lost the plot on trying to recall what this was originally shimmed for or what size.....

Thanks

If you know how to measure head clearance, shoot for somewhere between .025 and .028 in, or .6 to .7mm. The number of shims may very from engine to engine, even within the Sirio line or any other engine for that matter. It's best to measure the individual engine.
