So I’m ordering parts gaskets etc from Atlantic British watching the strip down and assembly vids tech said becarfull if check heads for true and they are good don’t rush to get them machined if they have been done before bolt holes might not line up. So how do I know can machine shop tell me I thought while it’s there I would get seats and valves ground too can they check thickness accurately. Thanks all never worked with aluminum stuff before just cast iron heads.

 

Feel stupid now lots of good remarks on this thanks
