Pieces of steel in cylinder??

Thanks guys. What’s the opinion here on reusing the valve springs? The old heads won’t be reused, but I do have a pair of 340 X heads with rocker shafts/rocker arms. I have new valves and seals for them, but still have the springs and retainers from the other heads.

Also, don’t hesitate to let me know if I stray off topic here.

The X heads might have too much flow for a stock 318 rebuild. I'm sure others on this site have personal knowledge about this. 340 springs have higher pressures than 318 springs and are only necessary when you use a bigger cam. X heads would not have hardened seats. There are better heads out there for your engine with hardened seats.
