: intake=1.92 : exhust=1.67 : : valves=3.59 : : .040 over =3.44 : that would need a big notch in the block Just for ref. the biggest valves I have put into a SL6 head with-out a block side wall notch was: Intake = 1.875 Exhaust= 1.535 I could have gone a tad bigger on the intake but the exhaust was with-in .030 of the wall. This was on a .100 overbore. (3.50) I had to sped a lot of time getting the head centered over the bores and also found that some of the valve guides were not machined at their proper locations. I would say that most SL6 engines do not need to go super large, 1.75 Int. and 1.5 Exh. is fine DD |
