Boosty be very careful with the heads on that car... Torque right to the spec and thats it... Too much and you'll be inserting helicoils, at which point it may be easier to remove the head..
And keep the Pushrods in order as the intake and exhaust will be different lengths, I forget which is shorter...
Other than that it shouldn't be a bad job
Also Make sure the Gasket kit has the Oil pump drive shaft O-Ring( Formerly where the distributor was parked )... GM went to the DIS on this engine, but they left the oil pump drive shaft from the old distributor set up.... So there is a plug under the throttle body... Usually with age they tend to start leaking oil there... Sometimes pretty bad..
