I have a very similar set of heads. Like yours, mine are the later 360 casting with the offset pushrod holes. Mine have been wildly ported, use a 2.02 intake valve that is 5.02 long, they have bronze bushed guides and were modified to use a W5 large port intake. They have also been O ringed and have brass oil restrictors in them. The ones I have are marked CTA 25 and CTA 26. Every exhaust port has been number stamped.
I think the CTA is a head shop marking maybe? I was told these were on a NHRA Super stocker when I bought them. Very odd heads for sure so I am somewhat glad to see another set. Although mine are not Mullen Modified like yours they do have the same base head.
Good Luck with them and I hope they do the job for you.
