And dee, how long would a brand new OEM ca18de headgasket last with moderate mods? Mostly just bolt ons onto a ca18det.
you'll be fine with oem headgasket... just make sure its tuned properly. tuning is key with these motors. detionation likes to rear its ugly head if anything gets out of whack (ie. poor intercooler, poor engine cooling, poor air/fuel ratios, etc...) a stock headgasket can take more of a beating than most people are going to put on it. there are countless other ways to spend $300 (exhaust manifold? turbo? intercooler? injectors? engine management?) rather than get an aftermarket headgasket.
I also like the inherit safety factor of a stock headgasket... if something is going to blow, I'd rather it be an easy to replace (and cheap) oem headgasket. Headgasket change can be done in an afternoon... pistons/rods take a full day (maybe more). Also keep in mind you have to have the block and head surfaces machined flat and smooth if you're running a metal headgasket, whereas with a stocker you just have to clean up the mating surfaces
