[DeTomaso] Head bolt size - engine pull

[Garth Rodericks]

Call the shop that did the build. They might know. 

>From CHI's FAQ page:

Q : Do the heads have all the standard accessory bolt holes on the ends? 
Ans : Our
heads feature all standard Cleveland accessory mounting holes, and as
of Nov 2005 will also feature all factory Windsor accessory mounting
holes as well, making Clevor - Boss conversions easier than ever before.
