LT1 Swap, 3rd gen rad. Gen. ques. on rad hose routing.

Does it make a difference if the rad hoses go in the top or bottom of the rad? for 3rd gen rad and lt1 I would have to cross the lines.. so to speak.. hose from thermostat points to pass side but connects to driver top and other rad hose points driver and connects to lower pass.
??

thanks.

the Thermostat opening outlet goes to the bottom of the rad...the outlet on the drivers side goes to the top...

the LT1 is a pusher rather then a sucker, meaning the coolant gets pushed through the bottom of the rad and is forced out the top
