Edelbrock Victor small block head……

That’s why I questioned it. The valve angles are different and unless you had a piston made for the 318 you’d crash valves. It all makes sense now. Thanks for the pictures.

Yup, that head has a 15 degree valve angle and most SBM heads are 18 degree.

That’s a sure way to get the valves and pistons having violent intercourse.
