Jeffrey, you know we're tight and I like ya, but, I aint fallen for this one. The specs (volumes) are one thing, the port shapes, guide sizes, short turn radiuses, valve distance to center of the chamber, plug location, chamber shape etc, are all going to be better. 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!!
