Here's what the heads are-3904390 1966-67 396/427 Closed . 325, 350 L-34/L-35 390, 400, L-36/L-68 98.4cc. Are these heads decent?

Couldn't read the bellhousing numbers but I found the numbers on the passenger side of the block, under the alternator. That number is T1100CXX, plus some smaller numbers. Can the block be identified with this number?
