Details:

Just not my heads. I bought them for my 331 striker with Afr renegade 220 heads. This pair of cylinder head rocker arm stud girdles is for ford small block Windsor heads. So I tried to install but realized bought the wrong ones.

That's why I m selling them. They are new and of course never even ran or used. I m asking only $120.00 so I can help cover my losses. They will fit 99% sbf heads of course with standard stud spacing.

They won't fit Airflow Research renegade cylinder heads.
