Hey, just ordered my b17 headgasket and arp studs from Inline4.com... the studs were $145, the gasket $72...and thats shipped to my door. Contact Hondata from their website and they will tell you the closest distributor. I highly recommend it too, i have it and its way better than the stock crap. Ive heard that my have out an exhaust manifold gasket as well? anybody know? Also, is it acceptable to use engine degreaser and water to clean the combustion chambers? thanks
