Those numbers will tell you what size it was when Nixon was President, may have been cut already but even in stock form 1600 85.5 pistons will fit those holes. 1300 heads need cut to fit the bigger cylinder. |

also the combustion chamber is smaller in the 1300 heads, and using them with 85.5 cylinders makes something like 9:1 comp ratio so beware of that. _________________ Fritz Custom Products

That will take shims to correct, or at least improve. |
