I really appreciate the responses, so please keep them coming. Shawnlee, I don't want to sound like a jack @$$, but BOSS 429 blocks are completely different from 385 blocks, according to Hot Rod Magazine http://www.hotrod.com/featuredvehicl...ford_boss_429/ . Do Cleveland heads just bolt onto 302 blocks? Do stock Cleveland manifolds work? What about BOSS 351's? Are there any repro BOSS 429 blocks, heads, etc.? Again, please keep the responses coming.
