DanielC Posted February 2, 2020 Report Share Posted February 2, 2020 You can bolt it on. But it you bolt it on a L-16, it will have less compression, and may no run as well as the 210 head stock on a L-16. Quote Link to comment
datzenmike Posted February 2, 2020 Report Share Posted February 2, 2020 A lot less. The stock 210 head is almost 8.6 to 1. Any open chamber head will lower it to 7.7 Quote Link to comment
