What size are the head bolt holes on GT-40p heads?

What it says....i've read its 1/2". That makes sense because they did put them on the lightning and i doubt they made two different batches with only the head bolt hole sizes being different.

A buddy of mine cleared it up for me i think.....

95 Cobra R and 93-95 Lightnings just have standard GT40 irons. Only explorers got the gt40p. R's and L's ford just drilled out the head bolts to 1/2 inch.

So the gt-40p's should have 7/16" holes.
