Head Gasket Leak question

[remist17]

I built a 383 stroker and assembled the engine. I am using vortex heads. I recently put coolant in the engine and pressure tested the system. A small leak formed on the lower section of the head by the #7 piston. Close to the outer water jacket hole. I have not started the engine. Do you think the gasket will seat itself if it warms up or do I need to pull the intake, exhaust and head? I was hoping not to have to repalce the gasket. Sidenote I did not use any rtv sealant on the headgasket. Motor was square decked and the heads are new.

Your help is appreciated
