Making Aluminum Heads Legal for all SuperStockers

Nope we only need the 1 set for Ron's SSer. Next time on Bischoff's dyno we hope to clip the 800HP mark. Not a bogus number same dyno that many other SSers including Stacy's. Getting Grandpa to let her loose is a different story! (I tried to post pictures but the files are too big, look on my picture album.)

I have been through the process of trying to get alum heads approved for my Pontiac. NHRA has very tough guidelines for approving heads. The E-heads are virually identical to my 455SD heads, but they would not allow them because the combustion chamber numbers werent close enough to the stock 455SD heads. Dont think they will allow you to scoop them out cause they wont. Their exact words were that they werent going to allow us to make our own combustion chamber.

The reason you cant allow alum heads to be on all SSers is that you will have engines with passenger car HP ratings have the capability of high performance horsepower results. With the abortion done to the CC rules with some people getting 10, 20, up to 30 ccs extra, you can possibly get a 200HP rated motor making over 600 HP. Ooooops!! That has already happened!!!!!!!!!(about 5 motors I can think of probably more).

With the unscientific method of the AHFS and its slow correction factors....it will take 20 years to get them in line, then they all stop getting hit way before it is realistically finished. By design the AHFS keeps the bogus motors all at the top.

Lynn, your post was spot on about the AHFS. And as you said 600 ain't nothing. I just wanted to quote the above line to show how bogus the combustion chamber rule is. Heads are routinely welded and reshaped, material removed from the chamber itself. It all flies thru tech. The head shops quote and advertise it. And aluminum would make it much easier to hide, not that a good cast iron welder can't already do that on old heads. Everytime that something is allowed it is because some group is already doing it and instead of a vacation we all get a rule change/revision.
On the BBC aluminum replacement we did the guides and a comp valve job and back to backed steel and aluminum. Suffice it to say: Does anyone know who did the R&D for the Chev. replacement heads?
