they make spacers that go between the heads and the intake to compensate for the larger spaces created by the taller deck height of the 400. usually used in the case of using cleavland heads on the 400 or 351M.

i didn't know this, well i guess you learn something new everyday. An yeah i dnt see why it wouldn't work, although when i looked at the link you posted on the application chart all i saw was 302/351w. You sure the heads will bolt to the block?

why not just use Trickflow heads and no spacers?
search this forum for 'Windsor heads' and see what comes up, it's been explained several times. there's no reason to go to all the trouble to use Windsor heads on a 335 series

You might wanna check out pawinc.com. they have stainless valves, roller rockers, and a adjustible valvetrain kits for the 400. they have some purty neat stuff there for that motor, was the only place i could find my forged pistons for mine.

yes the coolant flow path is different, a 'reverse Clevor modification' would need to be done. pushrod length would likely be custom, and you'd need a valley cover that seals tight. that you were planning on spacers the differences of Cleveland and Windsor intake bolt angles would work itself out, but the front accessory brackets might not have anything to bolt to? the intake spacers might cause the distributor to interfere with the intake depending upon manifold design, you might need to raise the dizzy on a spacer or come up with another type of ignition system.
you were considering laying out $1700 for a top end, why not just do it the easy way?
Edelbrock, Trickflow, CHI and AFD all make 2V cleveland heads that will accept standard 351M/400 intake manifolds and not cause any other problems.
BTW, you can do as much harm as good if you don't know what you're grinding on. and heads after 1975 have restrictive exhaust ports that can't be fixed with any amount of porting. there's a water jacket in the exhaust port
