You can also go with the stock headgasketts, they have proven to hold the power as well. It's a shame HKS doesn't make the metal stoppers for our application. I had them on my built 350 and they're the best hands down!

yeah if i build it will be NA and higher compression for more power. so stock or even thinner gaskets . on my kawi 600 SS, kawi made i believe 4 thinner gaskets than the OEM one. i think i went second from the lowest and got a nice boost in mid range power.

Most people w/ VQ's build for boost, but doing a N/A build isn't out of the question. Just a matter of what you want! I don't know of anyone making a gasket set for N/A so your best bet would be to stick with the stock gasket set.
