Woofer 540 - the good, bad, and ugly

The Indy website has pics of the flanges here: [ame]http://indyheads.com/images/price2012.26.pdf[/ame]

I am not sure which of those flanges fit the -1 heads. Edit: The 2 1/4 inch tube flanges are about 3/16 too big all around the port. They may work but a flange that took 2 1/6 tubes would fit better.

So I may I will try Tubular Automotive in MA. They say they have a D shape port flange. We'll see. BTW, tubular also sells a bunch of bends with various angles. They seem like good people to work with.

TTIs won't work for you?

Don't you have to change the oil about every race with alkyhaul? I am open to options now that I have to wave goodbye the $7/gallon 110 leaded race gas I can readily get. F'in Indy...

Maybe I can use C12, otherwise it will have to be C14 or C15. http://www.vpracingfuels.com/racing-fuel
