Re: relieving valve pockets

Your port work kinda follows Barny Navarro's theory where the air/fuel flow forms kind of a rosebud up and around the head of the valve instead of across the deck i would love to mock up one of these engines or maybe a flat head brigs or something just as disposable to see how it flows on a flow bench with a milled acrylic head to watch the flow. As way of the carbs I don't really know how they would react to that does the L8 fire like right down the line like once the intake of cyl 1 closes the intake of cyl 2 opens? Weber carbs and there variants are notoriously hard to tune and they are designed for one venturi per cyl. I have a friend who races 6cyl Chevy engines and the 292 style engine have simiesed intake ports and i asked hip how they work on a high performance engine and he said that the one port is feeding the 2 cyl one at a time so it may still work. I had even considered making a log manifold and using them just as a side draft carb similar to first gen Vetts and their carters but again there may be a tuning issue. If anyone out here knows someone who deals with European sports cars Triumphs Mercedes Ferrari ect they may have the answers.
