eddy's tuning differ from j's

i have recently changed from j head's to eddy's. what should i focus on such as tuning and timing.
with nothing changed the car doesn't want to start when its warmed up. also seems to take a little more gas at start up.

how much timing should i take away,and should i give her more gas or you tell me(is this even the right direction).

much rather ask you guys than sit on the side of the road and wrench.

thank you, AbodyHotRod
