383 knowledge anyone?

That was Andy F's engine. It did die of oil starvation...lol. It also was not a 383 anymore. Personally, I would use the 383 for 383 builds, not much else. I like tha fact they are short stroke and rev really well. The heads you have are early heads, using 4 bolt valve covers and bolt down rocker stands. I think it was 64 when the cast in stands and 6 bolt covers were used.
