will a 93 7bolt 1g n/t head fit on a 90s 6bolt 1g 4g63T?

[nightspeed87]

Just wondering because the 90s 6bolt motor swap head im using has been too machined down and the machine shop cant machine it anymore from whoever had it in past, and say I need a whole new head, and the valves are bent in the motor?
I have a 93 1g 4g63 n/t 7bolt head/ engine laying around but I dont think the parts are interchangeable.
To be honest I most likely will just have to scavenge for another gst head, but will the gst head have to be a 6bolt?


Would one definitly think there would be piston damage if a few valves are bent?
The whole motors going to be miked and machined and new bearings are already about to be thrown in and new rods and crank, and the parts are on the side ready to be dropped in, just wondering about pistons. And is there any good valve train upgrades to go in incase I decied to upgrade instead of tossing some stock valves in ?

Once you strip down the Cylinder head they both should be the same, sensors on the exterior, CAS, and what not may have different locations, but they should be interchangeable with no problem.

As long as they both are 4g63 motors the heads should swap just fine.

If you do end-up doing this swap, don't forget to swap your turbo cams as well.

what would happen if I use n/t cams I think i remember hearing they got longer duration? Maybe not, but has anyone every used n/t cams on a 4g63T and gotten performance out of it?

( I eventually want 264/272 cams though but dont have money for it now.)
