Best way to VVT delete?

OK, so it's looking like I finally have a good plan after confirming that the Eco crank and cam sensors will work with Microsquirt. I will run air filter - MAF - propane mixer - turbo - cable-TB along with crank and cam sensors to fire my coils sequentially. I'll use a 2.2 head to eliminate VVT and the LE5 intake with a cable TB adapter to run an L61 TB. I may also look into trying to adapt an LS1-style TB but it's a lot bigger.
My understanding is that the L61 gained the cam sensor when they went from batch to sequential firing of the spark plugs?

This is a 2006 2.2 listed near me but that is the cam sensor hiding down there underneath that evap solenoid, isn't it? is the owner mistaken on years?
I also looked up an '08 L61 on Alldata and it is showing VVT. 07 is the latest non-VVT I found.

I think it's been cleaned up good. It has 110k miles. But since I only need the head I'll take it for $150.
Since I need a cable TB now, I'm thinking of using a universal 70mm with adapter. Seem logical?

What about gaskets and head gasket? Is there a set I should get? Any affordable timing chain / guide upgrades I should do at the same time?

I picked up the engine. While he did get it very clean, he also painted it with dollar store silver, which ends up looking just like the factory new aluminum.
It spun smooth so I gave him his $150, threw it in the bed of the truck, and went home. Before I start tearing into things I need to decide if there's any cheap upgrades I want to do and get the gasket set in-hand. I've heard there are upgraded timing chain guides but haven't seen them anywhere??? I don't think that the chain itself is prone to failure, but the guides break which creates slack and allows it to jump timing. That's what happened to the junk mock-up 2.2 I already had here at the shop. (Bought for $50 a long time ago.)

That $150 2.2 wasn't in nearly as good condition on the inside as it looked on the outside!
I guess it's a good thing I was only after the head. #1 rod bearing was missing. There was no seal on the oil pan though and both the rod and crank looked fine. I'm thinking the guy I bought it from just pulled the pan and a rod to inspect and forgot to put the bearing back in after. Doesn't matter.
The head looks OK, other than just dirty with old caked oil. I would like to put cam bearings and maybe springs in it but by the time I do that I might as well re-build the entire head, which I'm not really into doing. Ran out of time but I'm going to clean it up good and go from there.
