as it says.....for a 87 350 V8. i checked out the site and it doesnt say if they are centerbolt heads or not. i want to know the numbers for 87-up 350's...thanks

 

Just looked at a set of Iron Eagles (similar head but in cast iron) and they have provisions to take a centerbolt valve cover- snall threaded holes for the 4 valve cover hold down bolts. The intake maifold bolt pattern, however, is for 86-down type intake manifolds. I wouldn't worry so much about the valve covers as I would the intake bolt pattern being for an 87-up style intake.

Dart's website says nothing about intake bolt pattern (so I assume they sell both versions) but I couldn't find any other into breezing through their website quickly.
