The bent pushrods would leave me to beleive that the piston let go 1st. Even with the minimal timing 15psi is too much for casties without an intercooler. especially with the poor effeciencies of the S/C14. But I'm not crying any. apart from the financial aspect, (this short block cost me $300 to freshen up) I kinda get a kick out of building engines and then destroying them. (well I enjoy screwing the living fukc out of them, and sooner or later somethings gotta give)I'm still trawling the piston catalouges for a piston to suit my A15. the E5 piston (I think) has a lower deck height, but the smaller dish volume means that the CR would actually be higher. A mate gave me a set of 78mm ones that he used for 6 months before going to 79mm ones. They are a good option, but they also need the small end of the rod opening up to 20mm. The bloke who does my engine machining said the last A15 he did this to he made the pins fully floating, and machined circlip groooves into the pin bores. I do like the idea of floating pins, and I an almost put the circlip grooves in myself.
