516 head question

I can’t imagine that package of parts having less than 1.900” IH.
You’ll likely end up needing to shim to get there.

Unmolested 452 head, Ferrea f5055 valve, comp 612 locks, comp 741 retainer, and also a comp 1730 tool steel retainer(the TS retainers have more installed height).
A-741 retainer(1.928”)
B-1730 retainer(1.978”)

**I have seen where there can be slight variances in IH for different batches of the same part number of retainers and locks.
