datsun229 Posted August 28, 2023 Report Share Posted August 28, 2023 I had a question can I use a l18 head on l20b block? Is it possible Quote Link to comment
datzenmike Posted August 28, 2023 Report Share Posted August 28, 2023 The A87 head was on L18s. It's open chamber and will work quite well on an L20B. The head ID is cast into the lower edge between spark plug 1 and 2. The '74 610 in North America was the first L20B and it was an A87 head. All L series 4 cylinder heads will interchange, though not always the best idea. Quote Link to comment
Stoffregen Motorsports Posted August 28, 2023 Report Share Posted August 28, 2023 Get the two common Datsun performance books. The info in them is old, but still pertinent. Quote Link to comment
