440 power gains/ aluminum head advantages?

yeah i'll probably verify it a couple times the kit i got comes with a piston stop so i'll just mess with it until i get consistent readings. i also bought a single solid lifter because from my understanding it makes it a lot easier to degree and get consistent readings with a solid lifter installed

The other thing is a way to move the timing just one or two degrees, offset dowel bushings are nice, the top gear is drilled out on dowel hole to adjust either way. Stick the appropriate offset that’s needed, might have to do again (they’re color coded for degree. You doing great, confidence is your friend!
