like chris sed,
for my money, i wouldnt use the block. id rather do it properly.
its not about splashing money about, it just that i dont get enough spare time to do things twice.
normally i just smear a thin grease, but i think you will need a good gasket paste for that.
i dont like grinding aluminium heads, but if you have to. make sure the company leaves it to cool properly. and i mean properly. then give it a finish grind.
quality aluminium heads are heat treated when new before grinding or cutting. it makes the machine work easier, and the aluminium doesnt stick or clock the cutters or grinding wheel. however on a regrind you will get some areas that will cool and relaxe more that others. so a finish cut is needed when done.
ive not used my J&S 540 for a long wile, but i would always clean a true the wheel with a diamond, and leave the head or block for at least 30 mins. before i done the finish cut.
