I'm re-installing the head on my 1987 Esprit 910 engine. Since I'm using the new composite head gasket I ordered new B907E0224Z head bolts used on the 93 and later cars. But what I received from Dave Bean has a length of 7.25 inches where my originals measure at 7.56 inches. These will not work in my car. Has anyone else run into this or is this a simple case of Dave Bean sent me the wrong bolts?

The OEM ones out of my '85 measured 7.58" after several installs if that helps.

You're right about the 7.58. I just heard from SJSportscars and they stated the B907E0224Z bolts they sell are 192mm long ( 7.58 inch) so it looks like Dave Bean sent me the wrong bolts. Thanks for your reply.

I just received the proper bolts from SJSportscar. These are 192mm long and have the machined dimple,as shown in the attached picture, at the end to denote they are B907E0224Z and not an A907E0224Z.

My bolts were the dimple-less A907E224Z "softies", same length, just not as good a steel, replaced with ARP ones from JAE.

Yes, they have the reduced diameter on the block end.
