LT1 intake on LT4 heads
 

Is there any possible way to make this work?

I'm not 100% sure, but I don't think there's enough material in the LT1 intake ports to open it up enough to match the LT4 head ports.

Not without doing some machining to make em match. It would be easier to just buy an lt-4 intake.

They wont match up

more work than its worth,lt4 intakes range from 195-240.00...

Yep, if I remeber correctly I paid about $20x.xx shipped off ebay for one...

I agree, Chris.
Sure. There are 'variables' you did not include in your post, however.
Did you plan on raising the port roof (in intake) to match the port height in the heads? If your intent was to 'raise the roof' of the manifold port, use of the OEM unmodded LT1 intake, will result in non sufficient material above the port to raise it the amount necessary. If there would have been no intent to port the LT4 intake (if you had one), then the LT1 intake will fit fine, as ports are the same height, width and location, as an OEM LT4 intake. The use of an LT4 manifold ALLOWs the roof to be raised to match that of the LT4 head ports.

One more variable. I noticed you would be using a '94 LT1 manifold. True? In that case, double check your port openings in the manifold. They should have a nice crisp rectangular shape to them. If it is, and they are as expected, those intake manifold port openings are actually LARGER than the ports of an OEM LT4 manifold. Did you, or do you plan to port the LT4 heads? If you scrutinize your OEM 'as cast' head ports at the flange, the matching short side wall (curved pushrod side wall) is tipped (angled) in toward the top of the port. IOW, not a true rectangular shape to it. This will match the shape of the port in a virgin LT4 manifold. This shape is also consistant with the later ('96-'97) LT1 intake manifolds. This means.... if you plan on using unported LT4 heads, the (your) manifold port will overlap on the width of the LT4 head port. Not a good mismatch. Ironically, this same 'untrue' rectangular shape is normal for the LT(1) head as well. This means, your original OEM engine from the factory, had this same head/manifold port mismatch. FFT.

This info and more, has been posted several times in the past, if anyone was so inclined to do a search (both here and in 'advanced tech').

Thanks for the detailed response. Wound up not buying the heads, though. haha AFRs here I come. Thanks again
