I am a bit worried how much boost and revs I am going to give her because of the stock head so if any would give a heads up of a limit just post it here...

During the time I found a good deal on a set of D2 racing shocks. They are extremely sensitive on street and I can feel every little bump on the street (not comfortable at all) but at least rock solid on street corners.
Also I am having less wheelspin when giving her full throttle from a stop sign

Here is the update:

Boost as much as your fuelling is good for! I have stock head and head bolts too. 7300 rpm has been just fine. I can vouch that the stock head can withstand past 8000rpm as I accidentally found out twice ( dropped it in 2nd instead of 4th on the dragstrip.. whoops ). I wouldn't set it at 8000rpm though lol. My factory tach won't read past 8000rpm so Im not too sure what it went too. Is It bad when the 1nzfe sounds like an F1 engine? jk.
Set it at 7300 if it still makes power.

I just looked at your picture few posts above... make sure your pipes are bead rolled or the dyno session may get pricey if they have to keep putting back blown off intercooler pipes. May be fine at the boost you're at now........

I can say for certain that the valve train won't keep up for long past 8000. I did the same thing once only I was on a road trip passing a couple gravel truck and somehow managed to pull it to second from the limiter in 3rd. Motor went to 8600 and sounded like someone through gravel inside the engine. 3 bent valves was the result. Luckily the motor kept running and I made it there >another 200km. The funniest part was that it didn't even set a misfire code or anything.

So wouldn't go past 7500 on the stock top end.
