After replacing pushrods, lifters, valvespring and valveseals last winter, the 390 has worked very good :-)
But a small issue occured, not directly an engine problem, but its related to the engine.
A sun pro tach II was installed and wired as it should. A pertronix ignitor 1 and flamethrower coil are used and the original resistance wire is bypassed so the coil gets 12v.
The tach lights up similarly to the rest of the dashboard lights in my 63 Galaxie and it shows the rpm up to 2000 rps, but after that the needle moves a bit back, aproximately 1800-1900, and then it reaches max 2100 and nothing more, in spite that the engine has much more rpm
Some hints about what could be wrong had been great
