bigport 4ages are not torque to yield, smallports are.
i do headgaskets at work on average probably once or twice a week, i only replace headbolts if they are torque to yield, unless the customer wants new ones or unless its a falcon.
i personally hate torque to yield bolts, cause even with new bolts, a VERY clean thread and a lightly greased bolt, when your doing the final 90 degree turn they dont all feel even which disturbs me a little and i hate the feeling they give, like they are about to break 
on my own personal engine id get new bolts, but i definately wouldnt spend $300 on ARP bolts.
also VRS stands for valve regrind set, not value regrind

you shoud use the smallport bolts and technique as its the later one and the heads are very much identical exept for the ports etc. toyota changed the way they did the bolt because they found it was better.
mick
p.s it dosnt matter if there torque to yield or alloy studs if the engine has been done before you dont know what the hell the guy before has done to them.to do it properly you have to chase the threads etc etc.do it properly or get someone that knows what the are doing,and most mechanics dont know shit from clay in the engine building department.i only quoted the above to point out smallport,bigport, that is all not the work!
