Uprated 603 head off '91 350SDL. Comes with new-style, poptested injectors installed, injector lines, new lifters, cam.
Presently at an aluminum head specialist shop having all areas re-checked (and made right if need be) and the cam journals line honed to match the cam.
Basically a fully machined, ready-to-bolt-on 603 head with EVERYTHING except the gasket set.
I have so much damn money in this thing it makes me sick.
Yes, this will bolt right on to your 3.0 603!
$1,100 plus shipping.
