timing chain
i would install the cam straight up (dot to dot) since the TR224 has 4 derees of advance ground in if I remember correctly. You have to be careful with the rollmaster chain. if you look at the crank gear, there are 2 dots....one aligns with the keyway on the crank and will set the cam with no advance or retard, the other aligns with the dot on the cam gear. you'll see what I mean when you take it apart.
good luck.
Look at my sig see what I use with gas.
I recommend PY3600E, call Yank and they will make one custom for you matching your specs.
Fuddle seems to be doing well also (their price is good)
and of course I can't complain at all with my VIG
