With the backplate conversion, I just need to take the cover off my P47 Razorback to adjust the valve clearance and can rely on the engine getting the oil it needs to be properly lubricated.
It is an expensive modification and the money can be used for other things.
I have the money needed.
It may be worth making this investment.
I gratefully accept advice and opinions.

Ola, make shure you get the latest production/ version of the engine, it should have improved cylinder base
and intake plenum design, along with the new main conrod. I donīt know how much better the new
manifold design is with regards to fuel distribution and temperature, so you might want to have the MMM version.
I have not been able to find pictures showing the internals of the MMM manifold, so itīs hard to say.
For shure you would also want a "corrected" ignition timing ring.
(If you find pictures of the MMM back cover internals then please post here.)
