here's a set of heads we did at the speed shop a few months back, i decided to go another route with the car i did these heads for, i've been holding them for some one that was interested locally but they won't return my calls, so their loss is your gain, first $700 takes 'em
they have 1.89 / 1.55 valves, 119# on the seat, you can see the seat was pushed way out to improve low volume air flow and they have a 5 angle valve job, everything on them is new, valves/seals/ bronze wall guides/keepers/retainers/springs/ everything, ports were rolled for better flow but not over done, the new valves key up at stock height so you won't have any fitment issues, the new valves are 25 grams lighter than the stock valves, this will def make her rev up quicker, she's ready to bolt in with a low enough RA for MLS gaskets which are highly recommended
yes they do have the SC stamping on them
these heads are probably good for about a 30rwhp gain, springs are good for .575 lift, but the way they are setup you will see torque gains as low as 1500rpm, a comparable job done by any other speed shop is going to be much more than what im asking, i have no use for them so there's no point in me keeping them
shoot me a PM
