The Edelbrock head will be on the list shortly, it will have the Runner volume as listed from Edelbrock with an HP increase like all the rest. The mopar 452A head has been legal for a while, all of these heads including the iron Stage5 heads all have the big valve combo from the factory. My customers and I have been working with Edelblock for a while now trying to get the head "NHRA" legal and it looks like we have a handle on it. The 452A head and the Edelbrock is the same casting, I have the port design finished so now i am just waiting on NHRA!!!!!!!
