These heads came from Summit they are GM heads that have been Machined for screw in studs, guide plates and bigger springs to allow a 550 lift. 194 in.  1.5 ex

these are brand new heads.

$500

Also have new Comp cam springs   I think part # 981-16 but will check $50

These are great heads if looking to make some decent power on  budget, they are the same heads that I put on the Carerra motor, made 326 HP at 4800 rpm...

I would buy these if I still needed a set, good luck with the sale 2Sav..
