    FX140 vs FXHO cylinder head interchange

    I have customer trying to install a 04 FX140 cylinder head on to a 04 FXHO Cruiser. I've checked all the part numbers and the only differences in the head assemblies are the cams, head cover, and head gasket. Am I wrong to assume that if you swap the HO cams in to FX140 head it will work? Their mechanic is saying the valves are hitting the piston but I think it's an installation error and is out of time. Hoping someone has some experience with this specific swap.

    Thanks

    Re: FX140 vs FXHO cylinder head interchange

    I was told the only difference in the motors was the size of stroke.. I just built a Fx cruiser motor and the pistons have groves forged in them for the valves. And if he shimmed the valve buckets correctly and timed it I’m not sure why it would hit ...did it have a valve job? If so then the valves need to be re shimmed as this is very important
