Smith had a post on this thread that Edelbrock had made an offer to NHRA to supply Aluminum head's for all the Stock & Super Stock Engine combo's and NHRA had not responded . If they made the head's and it was not profitable how long do you think they would keep on making the head's ? Do you really think we would use enough head's to make it profitable for them ? It would go the way of the replacement Q-Jet's . You have to remember the Bean Counter's really run these companies . You are the last one that has anything to complain about . You already have a replacement head avaliable . Some of the Buick , Old's , Pontiac , AMC racer's do have a complaint .

Al, haven't you been paying attention; I said before go on to Edelbrocks' website an you will see that they already have 90% of the heads that we are talking about. Indy Cylinder Heads and some other manufacturers will fill the missing heads that are needed. Lets' face it sooner or later NHRA has to start allowing replacement heads and blocks into the mix, because the manufacturers in most cases don't make the parts any longer. Your leave it the way it is thinking, is the reason that the car manufacturers are in the shape that they are in today. You have to look at the big picture, not just the here and now. What do you propose be done as the supply of available parts are depleted and no new parts are being made to replace them?

Neither Indy nor Edelbrock make a legal set of heads for the big or small Mopars and I looked at the Edelbrock site and they list only THREE sets of NHRA accepted heads: BBF, BBO, and BBP; nothing for Amc and Buick and they list no legal aluminum heads for any of the small blocks.

The big block Olds/Edelbrock head is legal in Super Stock only.

It is beyond me how Edelbrock never corrects their website.They claim that the Edelbrock Oldsmobile heads are accepted for Stock.If so,we both would probably have them,right?

Jim, in Edelbrocks' catalog they list part numbers for both small & big block mopar heads. Now as far as being legal, that is up to NHRA; no head is legal till they say so. You will also find the other heads you are looking for in there also.

The Edelbrock Mopar heads are no where close to legal. The valves are too big, the ports are too, and the runners are too big....the same can be said of the Indy heads. To be legal for big blocks they would have to produce at least 6 different big block heads.

Port size is not an issue, any competitive super stock head has the port floors brazed or epoxied anyway. You start by raising the port roofs as far as you dare, and fill in the floors to meet c.c. specs. and no, I don't race a max wedge (I have an LS1) as was alluded to before, I just think it's sad that the neat max wedge super stocks were a dime a dozen at one time, and there is only 1 that I know of running as of this year.

The correct 518M head is almost impossable to find now. Not all of them came with the correct valve size either from MoPar. I went thru 3 sets to find 1 pair that was correct. 2,14 intake size is a little to large if you want to go thu teardown. Mopar dosent care about anything except the SS/AH Hemis and the new "Paper Cars".

Actually Terry,

They made two versions. One was a stock replacement with the 2.08 valve the other was with the 2.14 like an upgrade head. We ordered a set from Chrysler and got them straight away. This was about a year ago. They were 100% better for porting than the stock castings. They flow 30 more cfm with a smaller valve than my Hi-Po Pontiac heads or Stacy's 428 heads. Of course they got good cc numbers from the NHRA cc fairy and we didnt.
