Hi Guys,

Got my self a bare efi cylinder head which i need to build the question i have is what size are the standard valves? and where can i get them?

as for the rest like springs etc i have a piper 285 cam tappets, springs etc which i will transfer over should i just take all the rocker arms and everything to or can i get new ones?

If so would any of you guys use motor factor bits from APD, GMF or GSF etc?

Thanks

Lewis
