<P class=MsoNormal><FONT size=4 face=Calibri><SPAN style="FONT-SIZE: 14pt">For
the past 20 years or so I have had a NOS Circle B 6 cylinder head on a shelf in
the parts room. For some reason I assumed it was for a TR-6 and would be ideal
as a starting point for an eventual TR-250 project. Must to my disappointment I
find it is a Mk2 GT-6 head. Likely it would afford too high a CR sitting on a
2500cc engine in stock condition. <o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT size=4 face=Calibri><SPAN style="FONT-SIZE: 14pt">The
question is……… Is it unreasonable to think I can open up the combustion chamber
to bring the CR down to ~ 10.5:1 using it on a 2500cc application
?<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT size=4 face=Calibri><SPAN style="FONT-SIZE: 14pt">Any
of you have the combustion chamber volume to achieve this using flat top pistons
??<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT size=4 face=Calibri><SPAN
style="FONT-SIZE: 14pt">Anyone out there have done this before? No point in
trying to reinvent the wheel. Serial number on head is
517528.<o:p></o:p></SPAN></FONT></P>
