A suggestion I have would be to deburr the lifter valley and pop for the added bucks for a lifter valley brace.
Yes, I know your not running a solid lifter race roller, but the tall hydro lifters still add more stress to the thin stock lifter bores , so why take a chance on loosing a nice block!
One other thing I might note is the high exh to intake ratio those RAII heads have.
The exh side of those heads on those heads flow right up there with what the intake ports flow, like 200 cfm@.550 lift, and that’s not even there peak flow either!
If you ever step up to running headers on the motor
You should change over to a single pattern cam other wise the headers will be a bit of a waste by over scavenging the motor and making jetting the motor right a good bit of a mess!
