First, you are probably blowing the head gasket because of improper rebuilds and other issues.
If you cannot do it correctly your self I would recommend using ALC machine in santa rosa, it was expensive but my engine is working excellent.
I was making around 430 WHP on my original engine on the stock head gasket with an upgraded ct 26 57 trim along with all the supporting mods.
I'm now a fully built engine with metal head gasket, and making at least that or more.
If you want to build the engine, you should follow the TSRM, and watch some of the videos on the 2jz rebuild from real street on youtube.
You will absolutely have to get this done at a machine shop
-4 angle valve job (if your valves seal well you can just lap the valves)
-Check the crank (probably needs a polish, again machine shop)
-deck the head and block to ensure they are straight and not warped so a metal head gasket will seal
-Arp bolts or studs to hold the engine together for the head.
after that, it's just normal stuff that you would need.
There are recommended threads on supraforums that talk about the SRfab oil pump drive gear, ARZ hard oil line to help make the 7m live against rod knock.
Hope this helps.. PS I'm in walnut creek, so not far.
