allot of bigger aftermarket heads have 1/2 bolt holes so they can go on either a 302 or 351, so if your putting these on a 302 you either use a different stud like thats in your block or you use a step down washer i guess you could call it. unscrew a stud from the block and see if the part that screws into the block is 7/16 then the rest is 1/2.

i completely agree with adder on this one, and I would really like to see him find a way to do that. but honestly dude if you had a mexican block all the info would be in the lifter valley. if it was a 351 it would say it, if it were a mexican it would say hecho mexico or some crap like that, you said it says 14 so you have a 14 or you just have exactly what 9sec said you have.

and adder, in this day and age not everyone has one of those digital image capturing devices
