Edelbrock 2.055 (30 degree back-cut) testing
Last couple sets of used Edelbrock heads I’ve done I’ve been down 10-15 cfm at .300 not hitting my target 200cfm. My last set of Speedmaster heads I hit [email protected] so I opened up a new set of Speedmaster heads to do a quick comparison. The chamber is clearanced more on the intake valve so with the 2.055 valve it’s really tightening things up. Here’s a few quick pictures showing the difference. Both heads laid out with the same gasket.
