That’s interesting! is there a good post you can recommend on it? My L24 engine nr is 01558x... Wondering if there is a way to find out if that one was equipped with an E31 or E88?

So I bought the car :) Its a matching numbers 1st series manufactured in 10/70z Which according to http://www.xenonzcar.com/s30/engines.html. should be an E31. The nice part about it would be originality as well as best compression ratio of all the heads that would fit. Thoughts on this? Where to get it? I am currently in Japan....Thx!

I look at a 1971 240z with an Engine Block number L24 015581. The head has a E88 Casting (which should be E31 for 1st series) and the valve cover I don‘t know. What are your recommendations? I was not able to check yet, if the block was mtching nrs...
