Reminds me of seeing when they did the Cleveland head on the 300-6 This is going to be a neat project. These heads have some advantages over the older style head, especially with the amount of compression you can run or boost very efficient. Can’t wait to see how it turns out.
Like I need yet another channel to peak my mechanical curiosity! I like this project! Would have loved to have been there for the question that started this project!
I've done this a few times. What you have will work...sometimes. The end cylinders will have issues with the valves tagging the bores unless you cut the bores oversize, if you only make one cut-and join in the middle. To get the bores centered up on the valves, you need to make a cut between each set of head bolts, and weld it up. It isn't that much more work and allows proper porting to make BIG power. Also the stock 300-6 cam will put valve lift WAY up, as it had a pathetic rocker ratio with the stock head. You will need good quality aftermarket springs, as the 300 will rev HARD with 862 heads and the stock cam, and if you get a good balance job done the only limiter is the pistons holding up. With forgings, it is trivial to hit 7500RPM, and with a good quality damper and as light a flywheel and smallest diameter clutch you can live with, 8300RPM was as high as I had the testicular fortitude to go with mine. Mine has the forged HD crankshaft, there are a few left out there if you call the rebuilders and ask for one specifically. Stock rods are good to about 600ft-lbs of output at the crankshaft, then they start to bend. DO NOT trust the stock rod bolts.
the 5.3 bore is 3.780 in.so with the bigger 4in bore i hope itll clear, i made a lot of effort, so i hope the valves will clear, fingers crossed, stock bottom end record here i come but i will use arp hardware.
@@TallGarage my Stock bottom End record is 418HP with stock 1988 F150 cam, N/A. And the problem isn't bore size, it's spacing. The LS spacing is 4.400", the 300I6 is 4.480", so if you center up on cylinders 2 and 5, then that means 1, 3, 4, and 6 are all 0.080" off center. If you center up on the two end cylinders so the head bolts on the ends line up, then all the cylinders are off progressively more toward the middle. If you center up on the middle two, then the end cylinders will have valves hitting the bores. When I did the ones for mine, I cut the head in six sections and welded up the faces to re-set the bore spacing to 4.480". You will need to weld up the gaps under the intake ports as well, and re-route the water into the head, as the water passages under the intake ports do not line up. Pushrods will run outside the block at the deck surface, and you either need to braze up the edge of the deck or machine a LOT off the deck surface to stop the oil leaks.
@@switch2472 Hey man thats great it sounds like you know a lot about this and i like hearing all the different ways to skin this cat, the bores on the 300 are .220 bigger , that should help clear some or that offset, ill let you know how it gose. As far the water ports all the water ports on my gasket were good but the two on the very end that went outside the gasket.
@@TallGarage If you think I'm the guy to beat you're about 200HP under the goal...the highest I've seen is a guy from NC who runs one in an altered roadster, makes just over 600HP on a 240 crank. You gotta be ready to spin the RPM.

That's pretty cool, I am working on a 351 Cleveland head on top of a 2.5 Jeep engine. The ultimate goal is cut a pair of Cleveland heads, weld them together and put it on a stroker 4.0 Jeep 6 cylinder.
Love what your doing, just wish you had been able to use Yates heads for the purist in me but I get the value difference, I was amazed in the 70s when this was done with Cleveland heads and we had some ford trucks with these motors and we upped the compression when rebuilding them I tjink with Windsor pistons and they were rocket ships in comparison 😀
I noticed that scraper your were using, it reminds me of how I made my own scraper using a very heavy ga stainless steel Hyde scraper I squared up the edge to something like 87° not square but perfect for scraping aluminum heads and blocks.
They USED to take 351 Cleveland 4V heads and cut one in the middle the middle and cut the ends off the other, then turn the middle section and weld it all up for a 351C 4 bbl headed 300L6, of course they used to bore and stroke the hell out of them as well.
And I'm over here still wishing they would make a modern Cleveland but now that everyone is jumping on the ev bandwagon and killing off the ice engine sadly it will never happen.Sorry,great idea and video.

Closer fit for the small bore would be the Mazda/Ford 2.3L heads cut and welded. Need special inline 6 cams made to the Cosworth cam specs to used with VVT.

have you considered leaving the head in 2 pieces and just welding shut the water jackets at the sawn ends? I am concerned about warpage and expansion is why I mention. Should be a way to tap in and connect to allow for coolant flow that can be easy to work with. I'm not familiar with the ford 300 head design, but it must be pretty bad for you to consider doing something like this.
its pretty bad, im almost doubling the CFW, and i could probably keep it in two pieces but itll be getting welded while bolted to the block should help keep it from warping and the machine shop will take the rest out.
I'd assume the head halves will be bolted to the block and torqued to spec before welding to ensure they stay lined up... This is a really exciting idea and I'm looking forward to following.
I know Cleveland heads have been adapted to the 300 six with amazing results. What kind of power are you aiming for? I would guess 350 to 400 hp is very possible.
