273 4bbl intake manifold question

That's over 7/16" diameter and will be plenty of clearance for the "standard" 3/8" bolts and angle...

That must be an LD4B... :thumbsup:

If I were Litz, I would buy that intake and then find a set of 2536178, 2658234, 2658920 heads locally. If he can't find any locally, I may know of a set near me...

Another option for him is to try the LD4B as is and see if the bolts will work, if not, he can enlarge the hole diameter a bit until it does, but that's a band-aid and I don't like to do that if I don't have to....
