I currently have a au2 xr8 with hand built tickford motor
It has a vortech supercharger and it's currently getting new head gaskets Done. Is it worth me looking into new heads while its apart? Am I going to notice any gains and if I look into new heads Will I need anything else?? Thanks it's a little new to me

AFR 185cc heads part number 1492. Pedestal mount versions shoukd allow you to transfer a lit of the components from your existing setup.

With the standard camshaft that won't be a drama. You won't need any extra parts beyond what is needed for a normal head gasket change, with boost I'd recommend ARP studs over bolts. You may require new pushrods to get the lifter preloads spot on, but not 100% certainty. Use the Felpro PT9333 head gaskets, and 1250S3 intake gaskets.

Without knowing cam specs then using the AFR185 head could be a problem. The valve reliefs in the factory pistons might not be large enough for the 2.02" inlet valve.
