Re: LB9 heads
Dad bought an old Chevy Coupe once that had a dish piston flat tappet 350 with LB9 heads #081s, it ran fine best I remember a very mild engine. I just remember it having the same heads as my 91 Z28 at the time when we went to change valve cover gaskets.

Re: LB9 heads
I had them on a old flat top piston 350 from a police car once. Didn't do a whole lot different driving or at the track. Not sure how much bigger of a valve you could get in them.
mill 350 heads and use a thin headgasket should be as good id think.
