i'm wanting to to use custom gs114 with flip flopped values with a ls1 fireorder for my twin turbo build 1-8-7-2-6-5-4-3 imagine it'd be pretty easy and cheap for a flat tappet?
Might be if there cam cores available. But at this time there are no core with that firing order on this planet that I know of. You would have to custom make it, and that can be done.
