re-building my VVTi 1jz, anything i shold do while it is apart?

[blingcommander]

so i'm at about the stage where i'll be chasing parts for my 1jz re-build. going 1mm oversize as the bores are pretty scored due to lack of care from the previous owner....

so other than pistons, rings, bearings and assorted gaskets. is there anything else i should do while it is apart?

[ecko]

valve stem seals, just get a genuine engine gasket set ($570 from amayama)
water pump and harmonic balancer

cheers man, was def going to do the stem seals as it was a issue on the older ones i'm lead to believe? and yeah the standard toyota gaskets were the best value as well.

any reason to change the balancer?

also how good are the factory valve springs? as it will prob be revved to 8+k in my drift/circuit car.

[Indelible]

been told by a few tuners that the valve springs are crap from factory, so replaced mine with brian crower ones.
stem seals a good idea same problem as older 1js ,

also i forgot to ask, head and main studs? same as a 2j?
