Default over torqued head bolts. Need advice.

hi i am new here and am looking for some advice on head bolt issue i may have created. I have a 2004 pt that i just replaced the head gasket with a fel pro perema torque and new fel pro head bolts. The issue is the torque sequence for a 2004 is

Step 1 = 25 Ft-lbs
Step 2 = 50
Step 3 = 50
Step 4 = Tighten an additional 1/4 turn

I miss read in my manual and did the sequence for a 2006
Step 1 = 25 Ft-lbs
Step 2 = 60
Step 3 = 60
Step 4 = Tighten an additional 1/4 TURN

I did the torquing in proper sequence and the bolts all tighten up nicely.
The question is should i take it apart get a new gasket and bolts are will it be fine to run as the head bolts are the same part number for both models and it not torqued that much over.
