396 cylinder head numbers
According to Mortec I have a 67 396 block #3902406 (375hp Chevelle 2 or 4 bolts) in my 65.
The heads have #3856208 and #3856210 they are 65 either from a 375hp or the corvette 396 425hp.
How can I determine if they are 375hp or the 425hp heads?
Are ther more stamps indication to tell the difference?
cheers Ray
