LT1 rocker studs vs lt4 studs

Long story short, i have a set of ported lt4 castings sitting in my basement, no studs. I have 7/16 studs in my lt1 heads right now, are they a direct swap over, or do the LT4s take something special?

Should be a direct swap.

'Real' LT4 studs [from an LT4 engine]are 10mm 'shouldered' studs, but 'regular' LT1 studs should thread into the holes OK..
LT4 heads that you buy from GM have regular nonshouldered studs in them...
