Actually , I reused the old gaskets even!!!! , I carefully separated them from the rocker covers & cleaned them with Kero, cleaned the mating metal surfaces of the heads & rocker covers, took the haf-moon thingys off the rear of the heads & cleaned & recoated them with the sealant , then used a hitemp silicone grey colour stuff ($14.00odd) from repco, both sides of the gaskets, then whacked them back on!!!!! Drove round the block to warm up the heads to cure the sealant & its stuck like SxxT to a blanket!!!!! Good for another 100,000 klm I reckon!!!!!!!!
