Always, When installing a bigger cam piston to valve clearance and valve retainer to valve guide clearance should always be checked.... :)

Unless you know of someone with the same set up and it all worked....

But it should always be checked due to manufacture errors....IMO.... :D

And make sure the springs will work , No coil bind, proper spring pressures..
