5.2 heads with bigger springs

Yes, lookin for someone who installed springs or machined heads for .500 lift.
That won't need and willing to sell.

Thanks, D

Don't want to sell but I bought the Procomp/Speedmaster iron magnum heads and used the Hughes springs and retainers. With .513 lift had room to spare with no machining.
You could start a thread in the wanted section.
