is it scrap?

[marco]

Got a cylinder head all good except tiny hairline crack between ports, barely visible. Is it scrap or can I use it? Cheers marco

Where about and between what ports?

You mean between intake and exhaust ports in the combustion chamber? I would not use them as you risk dropping a seat and causing a LOT of damage.

Yep, that tiny bit between the valve seats, is it worth welding as the rest is fine. The other head I've used as it was 100% fine, no cracks, replaced the one on the engine as it had cracked a lot and been repaired but didn't look too nice, had no confidence in it at all.

By the time it is welded, ground back and had the seats holes re-cut, new seats fitted, valves lapped in etc you might as well get new or good second hand ones. Just my opinion.

Fair point just don't like binning stuff (ask my wife)

knackered cylinder heads make excellent chucks for when jacking up the car I painted mine yellow so I know they're shit and took the valves out.
