No.

 

 

Not without hours of porting work. You need a head from 91 and up

 

 

If your putting the 96 block in an 87 to 90, and keeping the renix manifolds and injection, then yes you can do so.

 

Cams are different on renix (87 to 90) than high output and do put out better low end torque

Remember, you need new valve seals as well as to lap in the valves, check springs and retainers as well as for bent or worn rockers, and now is the time to check out lifters and push rods.

 

 

How is it that this 96 head has gone bad.

Pay to have it cleaned, lapped, new valve, new valve seats, and resy to go.

 

 

You are NOT going to be able to just buy a head and drop it on. If it's off, it gets rebuilt. No exceptions to this unless you like doing work twice.
