LEAN/sky high egts- I put a holley projection on a small block in a old truck I had years ago and tuliped the valves towing hard in the winter time because it wasn't rich enough, Smitty

Leaned out. Check the injectors. They most likely need to be flow tested and cleaned. I tulip'd 6 out of 8 intakes and dropped a valve seat on a SB Mag motor when the injectors began flowing poorly.

500 EFI Tulips valves
Thanks for replys, Eddie I did not do the job myself,the former owner tels me that he put works to the heads with new Comcam springs,but I can see that the heads has been milled and has a milled surface.This motor supposed to have a serie #0M050186 and if I got it right it should be with H beems rods, this motor has the 502 pistons and rods,I know the first models 500EFI had mostly the same internals as a 502 Mag MPI (not heads,pushrods,lifters and cam) In this matter I dont know the part# on the Comp cam springs and the lifters looks not like the origin 500 EFI,the springs looked to me to be very stiff,appreciate your oppinions here,thanks.
