You can't, er shouldnt try putting this head on a 94 block. Toyota offered 2 different 22r series blocks, 1st was talldeck, and 2nd was short deck. Youll want a tall deck block for using the 20r head. tall deck blocks were offered between 80/81, and 84/85. The details are out there search and you will find them, but definately do your homework this mod is not for everyone.

Whats left of a 85 Toyota, 22r Slightly Modified, Got propane, lots of tube n stuff.

Wouldn't it be easier to just do a good motor rebuild on the 22RE and get the performance upgrades for it from LC? I did mine with a few upgrades and I noticed a bit of power gain. I'm still using the stock air manafold but will probably get the upgrade from LC with in the next few months to gain a bit more power.
