 Heads worked only Anyone had the heads worked only on 37efi PD? I know it’s not going to help top end much, just wondering how much improvement I would see load carrying? My motor has 140hrs so I’m sure the valves alone would be an improvement. I’ve modded a couple GDSD in the past, but never a PD

Re: Heads worked only Yes it works, my stage 1 efi motors get a real set of heads, billet pushrods, mild intake work and a custom tune. It's a very good improvement over stock. Usually the 37 Pd has the hardest time stepping a load. This is the fix
