They make new pistons every day, so why worry?

I'm guessing the PTV clearance wasn't an issue? How exactly did you check it without taking the heads back off, or did I read that wrong?

This is the part that has me worried a little still. Dad has a Snap On bore scope, and he told me to run it down through the spark plug hole and watch as he rolled the engine over. The valves didn't come anywhere close to the piston but I'm still worried since this probably isn't the best procedure to do this. He seems confident in it so we'll just see how it turns out. He's built a ton of engines (35 year automotive career) so I should probably just take his word on things haha

Best of luck with that! There is a lot to be said between there looks like plenty of room and there is .xxx amount of clearance. Curious to see what it turns when you get it on the track!

Man that is recipe for trashing some brand new heads. It doesn't take any time at all to stick some clay in there and get an actual measurement.

It's funny, because my dad is the same way. Lifetime career mechanic and the last time I helped him rebuild an engine, he insisted on torquing the head bolts by feel. That was a junk engine in a junk car though, not a $2K set of heads on a race motor haha.

It's amazing at the kind of stuff you can get away with in the automotive field lol.
Watch his engine run flawlessly and never have a problem, whereas if I did something similar, I'd have a chewed up set of heads and pistons in the first 20 seconds.

He red lighted it and let out way early (he thought Rogersville only ran 1/8th), but 6.1 1/8th and he hasn't been to a strip in years

I honestly think the 6.1 is actually a messed up 8.1 but I'm not gonna crash his party

That's what I was thinking. But we won't be going to the drag strip again any time soon lol
Push rods for cylinders 4 and 8 decided to bend and 1 of the lifters collapsed on the second pass. He's ordered a solid roller cam so that'll be going in within the next 2 weeks. Then a proper fuel set up and hopefully the nitrous lol

Second pass he ended up doing a 12.5 quarter and still let off early. I have GoPro videos of them. Trying to get them uploaded right now
