Several days bro? Working 15 minutes each day are we?It took me several days plus lifting the motor to remove the long tubes
I'm not going to say LT's are an easy install for everyone but they're not that difficult. Driver side gets installed from underneath and I didn't have to remove the steering shaft, only had to remove the clutch fork cover. Passenger side requires more effort but maybe takes an hour to unbolt two engine mount bolts, push engine toward drivers side a little, drop LT down, tighten engine mounts. I've done this 3 times in the last 3 years, it's not that difficult. Each time i've used copper RTV gasket maker with zero issues with the supplied BBK header bolts. A dab of RTV on the header bolts and things are all good.
