Ok, heres your options if it were me doing this....
TFS Trackheat Heads: $1266.95
TFS Stage 1 Cam: $159.95
Scorpion Rockers: $236.00 (you can get cheaper ones, but its up to you)
Labor: $675.00
____________________________
total: $2,337.90
You can get all of that stuff, then save for a little bit on your intake, or buy the intake and save for a little bit on the install. I would get the major pieces now, and go from there.
-OR-
Get the Trackheat engine kit that comes with:
Heads
Intake
Cam
Rockers
Timing chain
Head bolts
Pushrods
and gaskets out the ass
all for $2,249.95. then all you have to do is donate a little blood to get the money together for the labor charge. i would honestly get the whole kit, then sell some old parts or something to get the cash for the labor. IMO it would be smarter to get it all as a kit so later on, the shop doesnt call you and tell you that your old pushrods wont work, or your timing chain is loose etc... i would get it all at once, wait a little bit to get the other 400 bucks for the labor, and go from there.
