Question for you guys, will I be able to use my header that I've been running with Indy -1s? (they are 2 1/4 so plenty big enough, just wasn't sure if they exhaust ports moved up or down from the -1s)
Trying to get more details from others for you.
Koffel's web site says, "The raised exhaust ports will accept a stock header flange."
The question is how much are these raised? (Compared to your previous Indy 440-1 heads)I saved this from a post by TTI years ago,
The Brodix are 3/4" wider and 3/4" taller than a stock iron head. The Indy heads are 7/16" taller and 5/8" wider than the stock iron head.
