These are BRAND NEW! They were assembled/ported by a local company that does our 1500hp big blocks, 9 sec hondas, ect. I will sell the cams/springs seperate. I am looking for $1200 for the cams/springs, and $1400 for the heads minus cams/springs, shipped if you live in the US. Please email me at timothy_truman@yahoo.com. They are ready to be shipped. Thanks!
