For Sale, 1 pair of SPII heads, used. They were on my 383 for approx. 13,000 miles when I spun a main bearing and decided to go 406. They are drilled for the steamholes for a factory 400 block, but can be used on any block. They were never ran after their last trip to the machine shop to drill the holes, and received new valve seals and a valvejob freshening, and leak testing. They were installed on the longblock before I went to Iraq, but were removed when I returned. Never ported. Would benefit from some exh. side porting, and make lots of power. They are the same as Summit part # 011250-1, which go for $439.75 EACH, I will sell for $500.00 for the pair. Buyer to pay actual shipping costs, I will have my shipping dept. pack them extremely well for no charge.

Also will entertain offers. Send by PM please. Also, I will post pictures, gotta find a camera, mine's lost. Buyer will have pictures before purchase.

 

here's some pics, you can see the new positive type valve seals. i know they look dirty, but it just brushes off, and i'll clean them before they ship. the majority of the head is painted black, so no surface rust there.
