360 LA installing Promaxx Aluminum heads

Okey~dokey. A few tanks of gas later and pulled a plug. That small spot on the porcelain is just a spec of gyrotis from uninstalling. I don't think I'd be able to do any better than this with EFI. Timing mark.. heat range and ring all reporting good. I'll eventually get around to cutting a plug down to see what's up at WOT.. but she pulls really nice with the fun petal down and I doubt I'll find anything surprising. Think I can call it a wrap on this aspect of the project unless something pops up. Thanks all for the input and for following along!

Next item.. T/A hood installation.
