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.

I would recommend replacing the valve springs... You need to match the springs to the cam that you select so you don't get valve float or too much pressure and wear out the lobes...

Have hardened seats put in for the exhaust valve seats...
