I was sceptical about these but they really work great. No leaks

Yes I ordered these and the bolts washers and the lock washers did not come in the package fully disgusted need to get motor done nothing but parts problems. Plus there’s no instructions

a little cumbersome without tabs or locating pins to line them up, but they've worked well so far.

works and made very well, but it would be improved if they had tabs to hold in place on the head while attempting to attach stock valve cover on top of it.

Needs alignment tabs on head side
