Jason:

The "439" block was used in late '68 [Passenger = 427 (390hp/2-bolt, 425hp/4-bolt Corvette = 427 (390/2-bolt, 400hp/4-bolt, 430hp/4-bolt, 435hp/4-bolt)] until early '69 [Passenger = 427 (335hp/2-bolt, 390hp/2-bolt, 425hp/2-bolt) Corvette = 427 (390hp/2-bolt, 400hp/4-bolt, 430hp/4-bolt, 435hp/4-bolt)].

As for the heads, from '67-'68 the L-88s did in fact use a closed chamber aluminum head, along with the '68-'69 L-89 cars. The L-88/ZL-1 switched to an open chamber aluminum head in '69.

Looking at your pictures, I noticed the heads were painted. Are they aluminum heads or iron?
