max lift cam in Vortec heads

I can to put the comp cam 12-235-2 210/218 @.050" .447"/.462 in vortec head without make work guide boss down, news spring and incresase spring seat, new retainer, ??

I have read that max lift vortec head is .420 and .470, but I am´t sure these data.

I can go 218/222 with that heads without mods?

It seems that the norm is that some castings are as low as .460" and others .480". You should measure all clearance before you run your motor.
