So as I might have said.. I picked up another 360, '77 or '78, and had it honed to the next size. .. that was .020
They revised the kb356....I like it.
I bought a new throttle plate 'source of vac leak' as well. Got the EP black nitro exhaust valves and EP high flow intakes. Gonna mill the quench pad. Can see the polish marks but can't feel them. I'll weigh them and compare it to the advertised.
