Now I will be doing this in the next 2 month so to minimize downtime I would like to accumulate the parts that I will be immediatley working with as well as simple upgrades while I am in there.

I will be doing heads and cam from LLoyd Elliot. Probably the LE1 package. Now this is what I was thinking. Since I am going to have the heads off and cam. I currently have 97 Z28 w/ bbk shorties and borla Since the heads will be off. Should I do this...

Headgaskets... any opinions to raise compression just a bit for power.
Mac Midlengths or PaceSetter longtubes
LT4 Hotcam kit which includes alot of small stuff and 1.6 rockers or should I go 1.7's and a bigger cam? I still want drivability but wanna run better than 12.5
New oil pump and New timing chain
attempt to home port the intake out.
keep stock throttle body and stock injectors
no cats to borla catback(already installed)

Now. ... Is there anything that I missed or any changes/suggestions.

If I did this what would you think my HP and ET's would be before and after a tune.
