B1 heads?
I had Tom Hemphill cut my old pistons from Indy for B1 heads so I could use them either head on my 572 years ago. I ended up using my hand ported 440-1 heads on it and ran 8.40@160mph in my Daytona and still had a few issues to figure out. Never had a chance as an oil line broke and I wrecked the car in 2010. I now wish I would have used those pistons in my new 572 but I bought Jason Digbys nitrous pistons and converter. I now have almost zero interest in running nitrous. That engine is together with B1 heads that I had flowing 420. There’s more there but I wanted to get the engine together. I did more work to my 440-1 heads several years ago and had the flowing in the 370’s and then had a local shop open them up for 2.250 valves but never worked on them again yet. Like someone said the Indy heads are more user friendly but a road less traveled is always more difficult. Plans are to probably at least pull the transmission and put an NA converter in it for some hits one of the days.
