These are the heads that are on the motor my father built back in the mid 80's. He can't remember who he bought them from. They have 40X35(35.5) valves in them. The only markings on them are above an exhaust port as "SCS 0770". I just had them cleaned and new guides installed to get them ready to go back into service on the motor.








Just trying to get some info about these, I realize they are old, may not even be in production anymore.

Small Car Specialties?

Yes, they came from Small Car Specialties. Our local racing association adopted a stock head rule around that time so I have no experience with them, but as I understand it they're comparable to CBPerformance "Street Eliminators" - the contemporary ones, anyway, can't say for sure what changes have been made to those since then.
I've heard that they don't dissipate heat very well...but I'll leave further comments to those who've run them.

Seems to be to consensus on the Samba too. I guess I'll find out if they run hot. They have no cracks in them and were in pretty good condition when I took them off. Thanks for the info.
