no power steering or assisted brakes would be really frightening at 160mph... glad you're okay

One day NA-T is finally running, next day you snap a valve...that was fast. Probably shouldn't have taken it to 160mph.

Start looking at a rebuilt head, new piston, maybe a rod. Back to the drawing board....

yikes, might want to put a cylinder honing on the list as well. Might want to think about completly upgrading the bottom end with some forged pistons.
