It shows up in the CYLINDER BLOCK AND HEAD figure alongside the 3TA, so the catalog ties this head to that shared top-end family from the mid-1960s. As a complete head with guides installed, it saves you the step of having guides pressed in separately when you're rebuilding the top end.
Our records show this part across a handful of catalog entries between 1964 and 1966. If you're matching this to a specific machine, check the casting against your parts book or give us a call before you order — we want to make sure the head you get is the one your engine actually needs.
