I have an 4.6 f150, trying to get the timing cover bolts back on, however, I'm not sure if I lost some bolts or what because the bolts I have are now not fitting, or at least 7 of them. Can someone please give me some insight on the bolts. The ones circled seems to be wider in diameter. Thank you in advance.

 

did you swap from Windsor to Romeo heads??

 

No, the engine was already a Romeo, which the new heads are. Hope that helps.
