Well I'm guessing it was the valve springs, or more so how they were set up, a stack of shims and no locator, the damper (with no locator) was bashing the shims and sending metal through the engine. I'm guessing some got through the filter. Also has the wrong retainers for the springs. Springs were pretty soft but hell maybe they are setup this way to loft the valve open or something with this square cam. One thing I didn't count on were the janky cylinders in the block, almost look rusted near the top of a few of them, we'll clean them up as good as we can... we gotta race.

I believe comp cams has locators,might have to be machined to fit heads. Look at short height valve locks too.What spring pressure are springs at? What fuel are you using?
