Why would Edelbrock build an EXACT duplicate of ANY oe cylinder head? They are going to install all known performance advantages to entice the buyer to purchase a set of these "replacement" heads. Like I said, otherwise, why bother? Original heads are out there. If you chose a combo that these parts are not available, you shouldnt lobby for an aftermarket part. (No disrespect to anyone that has, this is my opinion) If I decide to run a Max Wedge, I had better be prepared to search my *** of for a set of unmolested original heads. Carbs are also very hard to find too, but I dont want a Holley accepted on my 283. What you are missing is the oe heads cant legally have these mods that are already engineered into these accepted heads. Remember the angled spark plug adapters? And for the record, I dont think the Pontiacs or the BBC's replacements should have ever been allowed either! But, the barn door has been left open......

I look forward to drinking a tall glass of tea and discussing it at Belle Rose with ya, cant wait for March!!

Right on the only thing that makes these aftermarket heads 'replacement' is that they fit the engine block. totally redesigned port shapes. the only true replacement head that was ever cast by aftermarket were the horrible dart iron replacements that flowed even less than the heads they replaced. I have one simple question to those on here whining they need edelbrock heads. If your racing currently and have a few sets of your unobtainable,rare heads already why do need these new heads now?1 So you can try to do the restoration people a favor and give them your old heads? 2So you can have yours cause someone got theirs ? .Where does it all end?
