Bought a cylinder head from a local company. almost 6 months later my kzn130 is still collecting dust in the garage, head off. First one came, installed it, had numerous leaky valve seats/ valve clearances out of spec (also came with metal filings). They sent another, this one had incorrect valve clearances, one leaky valve, and a scratch on the deck rendering it useless. I'm paying 900$ for quality, I think that the fact that the company that makes them doesn't inspect them before they are sent off speaks to the quality. Fella named John Gabor recommended a well-known outfit in AU that makes good heads and rebuild kits but he can't remember the name, said if I asked here Rosco will know the name of the company? I just want an affordable and quality head that comes perfect and ready to go. (already looked into onllineautoparts: didn't find a head, partsouq: no kzn130, and I'm currently trying to contact roughtrax about their fully built AMC head).
