Have you run a DIAGNOSTIC SCAN FOR ERRORS????? Are ALL of the electrical connections good? If it turns over with the spark plugs removed, does it turn over fast or slow? Fast is good, slow is bad. With the motor turning over without the plugs in, you can eliminate mechanical interfearance, like open valve hitting a piston. IF there are no compression releases, the OEM starter may no be up to the task of starting a higher compression motor. I did a 105" to end on my 07 with no comprssion releases and had to upgrade the starter to 2.4kw starter.

Have you considered actual troubleshooting?
Charge the battery and have it load tested.
Remove battery cables, clean the terminals and the surfaces they connect to.
Clean the pins on the starter relay and the connector it plugs into.
Let us know when this is done, then you can start troubleshooting instead of jumping all over the place.

Great thread title Help another efi engine wont turn over!
Like as if its the fault of the bike.
I have a better title suggestion Help! I did a bunch of stuff to my bike and now it wont start.
Anyhow check compression, battery, fuel, spark, timing.

To answer your questions, yes I load tested the battery, I did compression tests , I've taken it apart checked , cams/timing , pushrods, starter, cables. I talked to ss, the guys who did my heads. SS said to check cables, starter, and to pump up lifters. I had already done that, I tried using car battery while jumping it. I got another set of the same lifters and cams that will be here next week and I'll try that. The guys who did my heads said they've seen cams with the timing marks ingraved incorrectly which is why I got another set. Thanks

East start don't need compression releases..
With 110 cylinder did the OP use head gaskets set up for a 4 inch bore.
yes I used correct gaskets
Could the ground cable going to the engine case be loose
unfortunately its not loose its clean and connected
If new lifters were used, a common mistake is to adjust the pushrods to deep and may have a valve hitting the piston..
The pushrods are adjusted correctly
If you pull the plugs does it spin over freely?
Yes
Have you measured the voltage at the starter motor when cranking?
