Just bought some used Edelbrock RPM 340 heads... for my Magnum

I bought a set of those junk Edelbrock open chamber heads damaged for 450.00. Never milled them and after repairing them, porting, and upgrading to a 2.08 valve have gone 9.70’s with flat top pistons in my 408. I’ll give you scrap price for them if you can’t unload them

HEELLL yeah that's what I like to hear. I get a real kick from taking supposedly worn-out cheap "junk" and making something good out of it. It's not optimal but for the price... there's a lot of potential still there, my thinking anyway.
