Finally pulling the trigger on parts!

Here is a pic of how mine ended up in the head. If I could actually grab them, that'd be great. But as you can see, I can't. AND, they are now snug and have no lip on the back of the dowel. I'm trying to remember how they got in there that far? I think I put the head down on the block to try and mess with the lock nut for the cutter and didn't realize they came out in the head. Thus, they were pushed right up into the head, much further than they were designed to go.
Though I did get one out. I just put the punch on it and hit it in the center of the bore and it came right out. The other. I'm on about 1700 whacks and it's still there.

Enough for it to wiggle out then you can grab it with some needle noses..

The 1701 whack got it a little more free. Then I could get needle nose pliers on it. Guess what was lodged in there? The blue painters tape. A small amount of that must have caught and got pulled up in there when it went all the way into the head. That didn't make getting it out any easier...

Good news is I went back, installed the dowels, and ran the cutter across all 8 pistons. 2 or 3 had minor shavings, indicating I opened up the radius a bit (which is good). Also means I was pretty close otherwise. The two I wanted to go deeper on, I was able to open up a little. I'll check them later after I grab the right tool to measure.
I do have one relief that cut a little deeper than the others, and it's getting pretty close to the edge of the piston. It's still fairly shallow there, and I know that's the thickest part of the piston, but I'm going to take extra care when I sand it smooth to reduce any hot spots there since it's close to the ringland.
Tomorrow will be me finishing the cuts on the exhaust side. It should go fast since I was able to run through all 8 intake valves in about 45 mins tonight. Practice helps, I suppose.

Geez, this is really hard to believe. Those tools should last for quite a while. I'd be pretty pissed if I bought the tools and they were dull after not even 1 engine's worth of use.
How fast were you spinning it with the drill? I don't think they're supposed to be spun too fast. Were the chips coming off the pistons blue?

jcsrt8 is a beast. I put one around a racetrack for the DriveSRT program, and it blew away all the other srt8's. Low gearing, 4wd, and sticky tires are an amazing combination!

It's coming along. The number 1 piston is not an optical illusion. The bottom of the cut is actually lower. That's because I ended up going .072" deep there vs the .062" deep I had it set to. Go figure. I guess I didn't have the lock nut flush on the feeler gauges. But, I don't mind going slightly deeper. I'd rather that than being too shallow and having a valve crash into the piston.
