I'm on the fence about if I'll leave the stock pistons in the engine or not. I likely have a set of L2289+.030" pistons coming my way for next to nothing, but if I use them, it'll be a complete engine tear down again and likely get some valve relief's cut into them for insurance. Or, I can try for up to 15 psi of boost, with intercooler and plenty of data logging.
Fortunately for inline engines, when changing pistons, if all the pistons weight the same it is essentially self balanced.
