[Healeys] Early BN4 Pistons

[RAWDAWGS at aol.com]

I am looking for some early BN4 "clamp style" pistons. Does anyone have the  
Hepolite part number for these? Were they used in any other application  other 
than the BN4? The block is virgin and I may be able to just go back  with std 
size but might need to go 20 over, waiting on the machine shop verdict.  I 
would like to just go back with the Longbridge set up for now and start  working 
on a BJ8 engine I have laying around so if I can limp along for another  10k 
miles with this engine I would be happy. If I were to find a set of BN6  
pistons with con rods would they work? Thanks in advance.  Scott
