Help with gtd rebuild

[MRTANGOMAN]

Goona be starting to re build my GTD in 2009
and would like to know if anyone knows of a good head gskt 'n stud kit
I'm going to be running a kkk24 turbo and increased boost.

i've looked thro' the threads an i need a 3 notch gskt ??
but for which engine ? azz or gtd (sb code)
some are saying azz and others gtd

i know i'll need to be using studs as the standard bolts are u/s when you start upping the boost pressures, i've got a good supplier of nuts 'n bolts but he needs to know what grade, i was thinking of 10.4 and using flange-lock nuts

i'm in the U.K. so need suppliers here please..
