Hi,
I'm currently building a 1275 i bought unseen (a bit stupid, I know). It has a 12G940 head with the following valve sizes:
inlet 35.6 single groove
exhaust 29.3 single groove
The seats need recutting because I can't grind them clean.
I was wondering If I need new valves as well if I get the seats recut? And if yes, can I use a size bigger than 29.3 on the exhaust? AHU1049 on Minispares looks kinda cheap compared to the C-AEG544 inlet valves I would go with, so I would like to have some race exhaust valves but they only come in bigger sizes.
some specs:
+60 bored (not my choice, was already +40 and it was a crap job)
I'm raising the CR to about 10.5:1
Evolution 1 cam
nural high compression pistons
CAM6232 crank
Thanks in advance!
Jens
