I asked the same question before. Here's a clip from an email sent to me from Tom Harold, aka TH (thank him not me --->
[email protected] ):
1.Heads: $400 or $425
2.Intake: $180
3.Vortec intake gaskets (specific to new heads): $25 (but you can reuse
these babies quite a few times)
4.Vortec stock self-aligning rockers: $50 (you can now get roller and roller
tip SA rockers. We had ours machined for screw studs and plates and went
with standard roller tips. I do not think that money was well-spent there.
It helps, but may not have been necessary. If you're on a tight budget get
the stock rockers.)
5.Cam, chain, lifters, springs, retainers: $300 (this depends on your cam
lift, as mentioned above. Only thing I gotta add: GET A MATCHED CAM AND
VALVESPRING SET! We got some stiff springs from one manufacturer and
standard cam from another---killed that cam upon startup. We pulled the
motor, tore it down, remachined it, put it back together with matching Comp
Cams parts, and it runs wonderfully now. Match your valvetrain components.)
6.Centerbolt valve covers: $30 (used, stock--Summit has chrome ones for
about $40)
7.Bolts for valve covers: I don't know 'cause some great parts counter guy
here GAVE me them!
8.Valve cover gaskets (specific to late model heads---can also be reused):
Ah, I forget. $20?
9.Intake bolts
Hope this helps a bit!! Good luck!
