Given the bore size a head like that might be a dog down in the low RPM range.
Mmm i do see that happening and yea with the 235 the valves are only centimiters away from the bore. But i can see so much gains if i get the combo right. I was at a 9.6 compression before on 317s best time has been 9.37 @144 with 21psi. Now im thinking with these 235 at 10.0 compression and a new cam combo i should be able to knock at the 8s hopefully.
