Edelbrock SBM big valve heads on clearance

Note the last line "P5153850"

I bet they are super commandos. I have them on my 408. Basically Aluminum edelbrocks with moved intake valve position, sold with a mopar perf PN, And they take a rocker arm setup that was never actually produced anywhere.

I had to take my heads to Harland sharp to get a set custom made. They are not w2, they are not t/a. They are a different offset entirely.

On a flow bench they weren't miraculously better than a standard edelbrock on a 4.030 bore. On an R block, they might be. I put alot of $ into having them ported, and the valves un shrouded, and I think I still only got 285 out of them peak, on Trickflows flow bench.

Mopar Performance LA Cylinder Head - P5153850

I'm pretty sure mine even had 2.1 valves. So typical "Mopar performance" contract someone to make something, data is half accurate, they make 200, and are discontinued before the ink in the catalog is dry. Hence....no rocker arms.

Not a bad head, but you won't be running a $500 set of rockers on them.
