				Head stud length and base gasket
			 
 
			Hi all,
 As per another thread, I am in the process of rebuilding my 1980 911SC RoW:
 
 - 190K Kilometres, engine never opened before, rebuilding due to many broken lower headstuds, did not spilt the case.
 
 - Had the heads rebuild by a pro.  Replaced all guides, stems, seals, valves and flycut 0.007" from sealing surfaces to clean up very minor damage caused by driving with broken studs.
 
 Questions:
 
 1. Before I removed the old head studs, I measured height to be 5.248" (~133mm).  I read that spec for this should be 135mm, but considering this was the stock measurement, and there is 0.007" shaved off the heads, I am thinking that I'll set the new (steel) studs at 133mm height.  Agree?
 
 2. Considering that there was only 0.007" (0.1778mm) flycut from the heads, I am thinking that the standard (0.25mm) base gaskets should be ok.  Agree?
 
 Thanks in advance and happy motoring!
