Came into a few extra dollars and I came across two sets of heads wondering which might work better and what a reasonable price might be for these. First is casting #14101083 with 64cc chambers 1.5/1.94 valves 110lb springs with .525 lift

the next set is #10088113 aluminum heads (same as on ZZ4?) 58cc with 1.5/1.94 and .525 lift.

I have never bought or worked on heads so I am kinda in the dark. I imagine I should change cam with this type of head swap so if you could tell me which cam would work best wiht this setup and anything else I might need to purchase or perform to accomplish this type of head swap would be appreciated.

 

I believe the 083's are swirl ports, which are the worst heads ever made. Definitely go with the AL L98's they are decent.

 

083s are iron L98 heads actually, the same as the ones that came from GM on your car.

They're about equivalent as far as power potential. The aluminum ones might be a bit better flowing after port work, but lack the EGR passage so if that's an issue for emissions inspection in you area you'll either have to get the add-on external EGR plumbing kit like Vette L98s had, or use the iron ones.
