the NOSS head is a great way to go. for the price u'll get it for u can' beat it! i myself am running a Pro Design Cool Head. i put mine on right the first time. no leaks, no buirning coolant or ANY problems. u could make the same mistakes putting any head on in my opinion, no matter what the brand. just remember to re torque several times and just keep checking. i put mine on. let it idle, then cool, checked the specs, ran it and putted round in first , then let it cool and rechecked and did this over n over till i was in 5th gear and really running it then made my final check on it. never sprung a leak or had problems with o rings. plus i kinda prefer the o rings
