what made think about jumping on selling my heads and made me look around for different heads was, I called a machine shop and to do my heads (this price is not seeing them, and he said was a little on the high side) Valve job, new roller cam springs good for .550 lift, screw in studs, guide plates, machine down spring boss, machine spring seat ect. $600 to $700 guide plates is all I really don't need done to the heads. as I'm planning self aligning roller rocker arms so I won't need guide plates. he said the springs for .550in lift and the roller cam & .550 lift were $145.00 plus machining down the bosses.
my cam with 1.6 rockers
GMPP HOT hydraulic roller, with 0.525/0.525 in. of lift and 218�/228� of duration @ 0.050 in. of lift.
$600 to $700 is a lot in my book. can't I buy new vortecs for $700 ? course the springs on them prob won't be rated for a roller cam. I called crane and the Crane Cam�s 10309-1 drop-in valve spring and retainer kit which is good for .560in + lift with no machining, and are rated for a roller cam, they cost $196.99 for the springs $ retainers. so plan is to order the crane 10309-1 springs & retainers and take the heads in for a valve job or what ever they need. plus pinned or screw in studs. I'm hopeful I can do that for around $200 or $300 tops, plus $200 in springs.
