When you put in TRW forged pistons, part number L2291F, you'll get about a 9.5:1 compression ratio.

I bought those heads from econodrag. They had seen pretty hard service. I'll be putting in new guides, valves, etc. Stock size valves only, as my machinist advised me that they are more likely to crack the thin area between the valve seats when installing the CJ valves.
