What cam should I get?

You should "dump" the oil and filter either right after the cam's break in cycle, or very soo thereafter. Dont wait for 100 miles. The additives to help the cam break in and the asociated bits of cam and lifter (very small particles) should be removed as soon as possible to keep everything else healty. I know many guys that run break in oil for months..I change it and the filter before the engine is cooled off after a cam break in..
