[Supras] Overhaul gasket set question

[Fred]

Hello
    What started out as a BHG has turned into a complete overhaul. # 5 cyl was damaged. So oversize we go. I am going to get  .5 over Toyota pistons. I have an 87T. 57 trim, no clip CT26, 550, lex, hks bov, cooleeze pipes, stock i/c,  3" defcon dp, 3" hks turbo exhaust, no cat, profec B boost controller.  I am planning on using arp studs with a cometic head gasket.
 Is it worth it to get a complete overhaul gasket set from Toyota and just pitch the stock head gasket or should I look for an aftermarket O/H gasket set? Toyota want $373.00 for the O/H gasket. Also have you guys used for bearings? Toyota?or do you think Clevite would be ok? any suggestions. 

Thanks
Fred
