Ok, i've been searching now for a few days for 2jz head studs, and summit racing is the only place that I know of that I can trust, unless you guys have somewhere else?

Anyways, the thing is i found two different kits
this one

and this

http://www.summitracing.com/parts/AR...n/?prefilter=0

my question is.. what the heck is the difference between these two kits besides the price??

and if anyone else knows of a different site where they're cheaper, please do tell me, plus a gasket kit for the head.

I've searched on here haven't found anything :/ and the vendors mainly seem to sell exterior stuff, so sorry if I missed something.

and ok that makes sense, I was so confused as to why the had that and I had to look up what that even meant, thanks for responding.
