What a jolly good Q ! HS 50's are still bit rare (not that the heads would change that much); anyhow : Donn; you may see interesting difference on blackplate if you do it with your standard components ; or if manufacturers engineer will perform this test for you . What I found ; they usually come with their own ; very much selected (say)1206's ; which in the end look on the plate as cute as your bathroom wall ; trouble is; as soon as you start to place your 805's overmetalised caps it will resemble more pebbled concrete ! So pull your worst part and tile with that ; to get most out of it .
