Finally working and a set of heads for me, or Matt
Waiting on a check to order some Ferrea 2.055 and 1.60 valves so I can finish a customer’s Speedmaster heads and a Victor340 was weather delayed today for another customer. So I don’t feel guilty working on my junk. I grabbed a set of Edelbrock heads with 2.02 valves that I ported probably 10 years ago. I stripped one down and did some more porting then I cut seats for 2.08 valves on my seat machine putting a 70-60-45-30 degree seat on them and a 30 degree back cut on the valve. Then I cut the spring pockets for bigger roller springs. Man was that job easier than doing them on my drill press. Well I was super pleased till .600 lift where they stalled. The 70 degree cutter left a lip on the shortside which I quickly hit with a sanding roll. After I play around checking airspeed in a few spots I’m going to reshape that lip and hopefully that will fix my issue.
