<DIV><FONT size=2 face=Arial>I just did a little grinding on an old TR6 head and
took some photos to send to a customer with the same question
yesterday. The photos are attached. You never know how much
extra material will be hanging out from the casting joint and getting close to
the push rod. Usually it is not a problem with stock ratio rockers but
with the higher ratio rockers the top of the push rod is leaning closer to the
rocker shaft and closer to the head in this area. The photo just shows the
rear three but any of them could be interfering. I always grind them all
as shown when I am prepping a head.</FONT></DIV>

Rods</DIV>
<DIV><BR></DIV>
<DIV dir=ltr>I going to be assembling a new TR6 engine shortly using tubular
push rods. I remember having to clear the head openings due to the
larger diameter of the tubular push rods but they are all running together and
I don't remember if it was on TR4, Spitfire, or TR6. If it was TR6 I'd
rather go ahead and take care of it while the heads on the bench.
Anybody recall which head needs cleared and if it is indeed the TR6 what
locations? Seemed like it was only in a couple of
spots.<BR> <BR>Thanks,<BR> <BR>Marty<BR></DIV>
