13s and 62s are not 72 cc like the manuals say. More like 77. They will get you 9.4-9.6 CR if they have not been milled.

Thanks for the advice, I found a pair of 62’s. The 6X-8,s had one crack and the 4x-4s were both cracked. The 4X-4s were in a running car with not known issues, go figure. Now I just need to match a cam for the 62’s.
