- replaced valve seals
- gasket matched the RPM intake
- build new wires and connectors for the EFI
Because of bad weather I couldn't do much testing, but it clearly feels stronger and it runs really nice...idling at 800rpm without any issue and no problem with vacuum.
If anyone with a 455 is wondering, if the old faithfull cam is too big... don't worry... I'm pretty sure a tighter LSA would also be streetable.. mine has 236/242/114.

What is the valve lift on that cam?
