SB Heads-ported,springs,etc.
These were going to go on my street 350 until I decided to go big block. Mortec shows these are 400 heads. I don't believe they have stock 76cc chambers though. With stock deck height and flat tops, compression was around 10:1. They have 2.02/1.6 stainless valves with Comp .550 lift springs. They have had mild port work done to them. Not sure of any flow numbers. I also have some pro magnum rockers I could include for the right price. I'm looking to get $200 for just the heads but I'm open to offers.
