    Chinese atc70 heads any good?

    Yes Honda is the best. But will the Chinese head bolt up and do they have the same valve sizes and cam?

    I ordered one of the heads and cylinder from eBay and bolted straight on and haven’t had no problems yet!

    We've had pretty good luck with the aftermarket atc70 heads too. If you're looking to take something off a different machine though, Chinese stuff looks real similar but it doesn't work with a Honda cylinder.

    Looking at dratv and tbolt they sell the lifan 110 E22 head as a performance upgrade for 50's and 70s. Increases the valves to 22/25 vs the stock 20/23. Anyone know if there are any issues with these heads and the tbparts 88 big bore kit?

    This thing was the Chinese parts is there so many variations and levels of quality that it's really hit and miss. Both of those shops seemed really knowledgeable about the products they sell and stand behind them. It may not be Honda quality, but it is on the higher end of the off-brand stuff. I used the tb88 cylinder and had great luck with it, buddy of mine use the dratv stock sized head and it was a perfect replacement.
