<VV> Corvair engine date code

[shortle]

I just picked up a '65 Monza 4 door (Free-you know what it looks like). This car has a tag on the inside of the front carpet that says "January 19,1965". The engine deck lid emblem is 110. The engine code is "T1109RH". This engine also has the big bolt heads. I am wondering if this may be the original engine for this car? Did Chevrolet have an engine sitting around for a couple of months before they mated it to the car? Did any '65's come equipped with the big bolt heads? Anyone?
This car also came equipped with the Evening Orchard paint which still looks quite nice (on the inside of the trunk lid).

This is not the LM Monza 4 door I am still looking for
