CYLINDER HEAD C/W GUIDES
Triumph cylinder head complete with valve guides, cataloged 1963-1964 under PN 70-4049A (alias E4049A).
70-4049A is a complete cylinder head, sold with its valve guides already fitted. It's a Triumph part, and it shows up in the parts book under the CYLINDER BARREL AND HEAD section, so this is the top-end casting that caps the barrel and carries the valve gear.

The catalog entries for this number run 1963 to 1964, and the older book form of the same part number is E4049A. Beyond that, our record doesn't spell out which specific model it belongs to, so if you're matching this against an existing head or barrel, check the details against what's on your bike before you order.
Buying it complete with guides means you're not chasing down guide fitment separately, which saves a step if you're rebuilding a top end from scratch. Give us a call if you want to confirm it lines up with your barrel before it ships.
