Re: Making Aluminum Heads Legal for all SuperStockers
For all of you that want to cry about the expense; I can tell you from experience. I have one of each, and aluminum head motor and a steel head motor so I know the cost for a fact. First the aluminum heads cost me more to purchase, but they where new not 40 years old, second they didn't have to be checked for cracks, sent out to be welded. Bottom line is that the aluminum head motor actually cost a couple thousand dollars less to build; best part is that I don't have to drain my motor at the end of the day. So; the expense part is crap! I don't care if the replacement heads are steel or aluminum, but it would be easier for the replacement heads to be made of the same material for sake of HP and weight that needs to be added. I said aluminum, because most of the replacement heads allowed now are aluminum; so why not stay constant. Finally some type of replacement has to happen in order for traditional classes, not GT remain alive and well.

These figures are from Jegs for NHRA accepted for a set of bare heads: BBP..$1512.00; BBO..$ 1534.00; BBF..$1200.00. I went to the Scoggins site and could not find a listing for a 401 head but found a 410 bare head at $ 1500.00. The price for a set of legal BBM heads will be in the $ 5000.00 to $10,000.00 range because they would have to be tooled and produced....no one make anything near legal at this time ( this estimate from Indy heads for first run). Couldn't find figures on AMC or any of the other small block combinations out there .....what do they do while everyone else gets aluminum heads? I stand corrected about the chevy BB heads, it looks like the price is about the same for a bare head. JimR

Re: Making Aluminum Heads Legal for all SuperStockers
The big block Olds/Edelbrock head is legal in Super Stock only.

What I'm trying to say is the same gripes that were heard from racers of "traditional" SS racers (same make / model / year engine in like chassis) would be the same arguments against non-oem aluminum heads being used today. I'd like to spend more time here but have work to do. So follow along with my poor logic and lousy comparisons.... GT gets a more aerodynamic car - SS has to deal w/ cast iron issues GT gets a newer car that's easy to find - SS gets a head thats hard and expensive to find GT gets a car that doesn't have 100,000 miles on it - SS gets a metal fatigued car GT says build one; your allowed - SS says, "I've had this car 20 years & not changing" Hopefully you can see my point that these things just keep happening with NHRA, everybody has their point of view, they all hunker down together and in the end life goes on. I'm for aluminium heads (about $1500 from Edelbrock for my AMC) because I don't think one group deserves an advantage over another. Will I rush out and buy a set tomorrow if approved? No, can't afford it right now. But if / when my cast iron heads start leaking all over I sure will appreciate that option. And nobody has mentioned thermal efficiency. Maybe the guy with a 8.5:1 compression engine won't benefit from aluminum heads? So let him run his choice.
