eh personally i wouldn't put much effort into a set of 1st gen heads.

VVTi style heads are where the flow's at. they flow ridiculously well. Valves are >1mm oversized compared to '95-97 heads, and even more over '89-94 heads.

Would they fit the first gen block?

kinda. they'll bolt on but won't just interchange. Because of the lack of distributors they would require a full custom harness and standalone EMS, as well as some fabrication to lock the VVTi function as the older blocks wouldn't have the correct oil provisions for the vvti mech.
