IHi have a vy L67 with mace memcal too using it daily for 2yrs now 0 issues (used your guide to install it) but I still have standard throttle body, I think you should check your firing order take note of what lead goes to what plug my firing order is 632541 also remove the heads off and have a look at the tops of pistons then see if it rotates freely once valves/plugs are off the menu
Hey Michael that’s where my heads kind of at too just difficult to do these kinds of big jobs with the area I have let alone my knowledge, I think I’ll give it a good crack how’s your rig going?
@kylenator329 just take lots of photos before you remove anything then you will know how to put it back, you might be lucky and just need head stuff like valves but most likely you timing jumped a tooth or 10 it has to come apart anyway so no harm pulling heads and timing cover check timing
