Oooof! that's not right. Hope there is some restitution for you. Do they leak OIL or COOLANT? What MPH/ET did the car wind-up running? Probably not great MPH because it's not the most aerodynamic set-up.
The car was pretty consistent in the low 9's the last time I saw it. I don't think I saw the car run at all in 2023. They toured around to some different tracks but I never happened to be at the same spot.
Heads are leaking coolant in multiple ports. I've heard that it can be a problem with the Big EZ heads, especially when they are opened up for a larger intake valve. We rolled the dice on this engine and lost. I have a lot of confidence in the -1 345 package. I've seen a lot of those heads in use and haven't heard of any issues with them.
I know a guy with both 440-1's and 572-13's that would consider selling one or the other. Same guy is modeling some 1.3 ish C/H 572-13 pistons around a 4.505 bore.
