Biggest problem with drip-fingers and baffles in OEM rocker covers is, nearly all interfere with more desirable full-roller rockers. Triple springs all rub each other to dampen their harmonics, and drying up the top-of-the-motor oil supply can quickly turn the valve springs blue.... which happens around 550F I think. 'Drying up the heads' with restrictors is an example of something that works in ultra-high-rpm drag racing but not on the street. Some WFO-Cleveland fans add pressurized lube-bars in their rocker covers that sprays on the springs. Short AN lines from a tee at the stock oil gauge supplies plenty of oil.
The baffles need to be pinched together and welded in that position then they stay out of the way of aluminum roller rockers. The drip fingers can be trimmed in length.
The aluminum roller rockers are bulkier than the Comp Cams stainless for sure. The stainless rollers are smaller and offer more clearance.
I'm using the Ford Racing aluminum roller rockers with Detomaso covers. It's tight in there but they do clear. No cover gaskets. Just siliconed to the heads.
There's a little work involved in clearancing everything but it's very doable.
using double springs with dampeners so yes there is a little friction there. The oil bath is a good thing.
