Im very indecisive right now on what headgasket i want to buy. ive read plenty of posts that say oem is good enough for most and others that say oem pops after a couple of months (sorta like mine). at first i really wanted cometic so that im confident my hg wont blow, but then im on a really tight budget and since i found out y8 hg's fit z6's im like wow 20$ and im good. i also need a timing belt and waterpump (its about that time) and arp headstuds (why not? im already in there). so its basically peace of mind vs budget.
