sense to be able to use all uniform length bolts on the intake manifold but also to have uniform tensioning of all bolts through heat cycles due to all bolts being equal length.
Never noticed the spacers on any other OEM FE intake manifolds.

Considering the amount of contraction/expansion I think it would be irrelevant given the fastener torque.

If I am on the same page: I have seen the rear intake bolts both ways. Was that a year specific change or different factory instalation?

I think its a moot point.I have seen lots of FE intakes (not marine) with spacers on the last two bolts.

Seen it both ways often.
The "equal loading" thing is pretty nominal on an intake bolt.
A solution looking for a problem....

Kinda my point Barry. If it was an issue, FE's would be blowing head gaskets all the time due to mismatched head bolts.
