Thanks guys. Mine has 2.08 / 1.60, 11/32 valve steam. 5/16 rocker bolts and same size of intake and exhaust runners. Basically is a Edelbrock head!
I'm running currently on 360" 3.58x4.000, 11.8 CR, Pump Gas, Solid Flat Tapped Cam, Tunnel Ram and with a set of Edelbrock ported by myself that flowed 310@.650". These heads already has 2.08" intake valves and a huge work on intake runners that has 195cc with std LA port. This engine produces 484WHP@6800 and runs 6.73@103mph on a 3300lbs a-body. Can runs easily on 6.5 with a better 60ft.
I spend a lot of time just making measurements on intake runners to see if I can do a decent porting work on these heads. So far, my expectation is good based at all that I saw.
I believe that making a good job, these heads can flow over 310cfm with the benefits of a large port can provide.
I will keep everyone informed about the progress. Thanks a lot for all information.
