They are interchangeable. You will need to block the head drain or tap one into the block. The 3 rib block internals are a bit smaller/weaker than the 7 rib though.

Hey there,
I am a rather big noob with this stuff but I was wondering what is needed to put a small port head on a big port block. I stupidly (I was 18 at the time) bought a small port head without looking what block it came with. It was also a very bare buy. No water pump or anything like that. Is it a simple bolt on or would it be worth trying to find a small port block/putting it into a small port corolla. Basically I want to make a fun trackish car that I can learn to wrench on.

You need to block off the oil drain if you are doing his , you'll see what I mean when you go to bolt the head on.
