I have had (for quite a few years now) an 85 MPFI engine with 10,000 miles on her. Those heads would also fit a turbo correct? But not a SPFI?

 

MPFI subys seem rare

Now the block itself should be usable for my 93 loyale SPFI car right?

I was thinking of maybe selling the heads and keeping the block for me

That is a very rare engine. Yes - techincally the heads are MPFI/Turbo heads - but they will be first gen turbo heads and they also won't have the passages drilled for the turbo oil supply. Basically not worth much since they are very prone to cracking.

 

The block should be a 9.5:1 block just like the SPFI's so yes - you should be able to use it.
