what kinda spacers you talkin about? an when i built my 400 i had the stock heads ' warmed over' a little cause i didn't know they even made aftermarket heads for the 400.

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?
thats why i was asking. idk if windsor heads will fit.

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
is it that they will bolt on but cooling and oil passages are different? sorry, couldnt find a good thread discussing the topic.

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

so do you think i should clean the heads i have (theyre on a 78) and take them in for core value, and get some 4V heads or earlier 2Vs so that i can port them out?
