That's an interesting point.
The rules (and I'm a rotary guy here, so correct me if I go off track, guys!) stipulate the if correction is done, that it be done in one location.
I assume (uh oh!) that rule was written in that manner to preclude people from choosing to "fix" one, bit not the other, leading to a net gain.
My question to the experts is: If you deck the block/shave the head, is that scenario possible?
If so, the rule is trying to be "self enforcing" .
I'm just trying to get a handle on it...it's probably fine as is, but....I just want to understand it better.
Yes, you could return the intake cam to OE and leave the exhaust cam alone (or vice vrs) after decking the head on a single head, dual cam motor. The rule as written makes a difference on any OHC V motor w/ a single belt/chain. As you deck both sides, they move down & in making the distance between the two cam centers different so the two cams see different amounts of change. Fixing it at the crank only corrects a portion of the problem.
