General consensus is anything much above 0.43" at the valve may result in the retainer clouting the guide. It was around that in mine so I machined down the guide and seal area slightly for my higher lift cam. Springs are actually OK, you just run out of clearance there well before the springs would bind. Plus a"bigger" cam can overpower the stock springs...= floaty.
