Anyone using a b303 cam and 1.7 rockers on their stock bottom end? Just wondering if there is any piston to valve problems.

I run the B-303 with FMS 1.72 rockers on a stock bottom end '85 with no problems. The combination works real well for me.

i had to fly-cut my pistons, because on the rebuild i had to deck the heads and block(blown head gasket). i was way below the minimum clearence spec.

I use a b-cam with cobra 1.7 rockers on a 92' stock bottom end. No clearence problem and I love the combo.
