1996 Pontiac Firebird Question: think its got a burnt valve, on how to tell and how to fix NEED IDEAS

Used JB weld to fix the hairline fracture in manifold missed a part so it blew out but trying again today. Pretty sure its got a burnt valve. Looking either for a quick fix to keep or a way to get rid of it. Spent 15 on the car itself and got almost 5 in it now -
Answer 1
ONLY WAY TO REPAIR A BURN'T VALVE IS TO TARE IT DOWN AND REPLACE ALL NECESSARY PARTS AT THAT TIME. JB WELD WILL NOT REPAIR THE LEAK U ARE TRYING TO FIX GOOD LUCK -
