Sorry guys, this is probably kinda a noob question. But I’m putting a metal head gasket on my SR, and when I pulled the head off the majority of the gasket came off, but a surprisingly large amount stayed on the block. I’ve been told to scrape it off, but being an aluminum block I’m a little skeptical? Anyone have any suggestions? ---

scrape it off, just be carefull. it is aluminum, but you still need to clean it off for it to seal properly. ---

by the way, i really hope for your sake it isn’t a copper head gasket, they are great if you rebuild your head after every 2-3 races, but if not, they like to clash with aluminum and rust. ---

no wire brissle. Use a razor blade and carefully scrape it off. The just use 1000grit paper on a hand sized flat surface like a sanding pad. ---

There are rubber buffing pads that go into air drills or die grinders, anything of the like. They work amazing. If thats not available then yeah, get 1000grit sand paper and sand away. ---
