1976 slant head

Hello folks I’m looking for a good rebuildable head that I can play with. Needs air injection ports for a slant in Bay Area California . I checked car parts website and went to the shop that was listed in Hayward but they couldn’t locate the part. Any help is greatly appreciated. Thanks in advance. If in east bay/marin/SF I can pick up during the week after 5pm outside those areas I’ll only be able to pick up on weekends .
