It may not be possible to use small caps. at the I/Ps of the "finals", due to grid to ground resistance limits. This is especially true, when "fixed" bias is employed.
As for blocking, I recall reading where 1 fellow was going to implement "PowerDrive" using ZVN0545As, even though positive grid current was not permitted. A rather high valued grid stopper prevented significant g1 current from flowing.
