4x4 sohc for my lve it has a big intake you cna use tape to make it smaller to fit your vacuum Printing: ender 3v2 PRINT VALVES SEPERATLY AT 50% speed or they wont fit... you can print the head normaly... i do 89% on supports (in cura) for the head so it doesnt make supports inside which are a really hard to take out... this has been in development for about 3 months now. this is a important project for me probly went through a spool or 2 of filament. need pilot g-2 pen springs. i think there 4, 4.5 for inner diameter and i think about 24mm or so tall. thats for valve springs and you need one lego cam and some other lego peices... i will post a video link of me putting it to together... i used stock cura setting for the rest of the info
