That is what it has come down to for me as well,
This is what I think happened:
HowellAutomotive sent me the wrong pistons. I ordered 10.5:1, but I have to have 12.5:1 given the symptoms. Either that or the pistons were not made for the longer rods that I have, but I don't think that is the case. I think I just got the wrong fucking pistons, which really pisses me off, however. Now that I have to replace them anyway, I am going to go ahead and turbo. I wasn't too impressed with the performance after the upgrades.
One thing that does have me confused however is that cylinder 1's compression is only about 225 while the others are all around 285. I wonder if I got one 10.5:1 piston and the others are 12.5:1. Given howell's record, I would not put it past them.
One more thing that urks me, is that I might have to go back to them to get the 8.5:1 pistons...
