| I wasn't aware of the difference on the heads between the 90-94 and 95-96 versions and just got into a problem. I'm building the engine on my '95 JDM Z32 TT and since I had '90 ported heads sitting in my garage with the "30" stamped valves and no cams, I took the "EG" stamped valves and cams from my '95 heads and got the machine shop to work on the seats and get the cams worked also. Now that we are getting the engine back together, we ran into a problem fitting my '95 lower intake plenum with my '90 heads since they have different intake and injector design. I also have the 740cc Nismo injectors and have the '95 style adapter kit in case I need it. 
What can I do with this? I have not many options since I'm in Peru and it's impossible to get parts for these cars...I'm already looking for a '90 lower intake plenum, but I'm pretty sure I won't find any....maybe there's something else I can do with what I already have. I'm not planning to use my '95 heads and rework the whole thing again, specially when the '90 heads are already torqued to the block.
