as above really, need to put mine back together after water house split, did have cometic and arp, but cant afford it right now, or a a while yet.

i can put it back together for £200 using standard stuff

or £700 as it was.

currently got 320 / 320 and happy to stay there for now, may push 350 at some point.

need to know if standard stuff will hold together

im sure there are plenty of cars running round with more then 320/320 and have never been opened up, i thought the arp's were reusable? or have they stretched?, if it was me i would use the cometics and standard bolts and put it back together that way, at the end of the day a new age sti uses standard bolts and some are running a lot more then you are and im sure if they do fail it wouldn't be down to the head bolts.

Running my Newage STi at 453bhp & 386lbft. I changed the thermostat mind you to a Zero Sports version. And that has helped cooling with the power and ALS being run.

If on a spritied drive I tend to check the overflow a little bit more often than normal to be on the safe side.
