I dont use a gasket anymore. The briggs gasket always blowed out for me. Just sand your oil pan where the cam gear goes against the oil pan make sure you have end play on the crank. I use hondabond,yamabond,the gray stuff and i also use studs in the block and double nut them.Sometime you to cut the cam where it goes into the block just be sure the cam has some clearence. No more problems!
