we have the technology to attach the head to block with these. try harder.

I want to be able to reach in and yank a piston out in 2 minutes. stop with the excuses

Maybe if you use 4:1 compression or something.

>>28511959 (OP)
I prefer my cylinder heads to be Lego System-compatible

>>28511959 (OP)
Bolts don't take much longer to remove than those things if you use an impact.

>>28512827
Yeah, the actually annoying part of engine work is all the cables, clips, and tubes that surround it

>>28512855
Buy an old flathead, problem solved.

>>28512827
>>28512855
this, the hard part of heads is as above mentioned and having a good quality torque wrench and a workshop manual for the torque sequence.

>>28511959 (OP)
Has this ever been done, or is op a schizo retard? Can't wait to mount the head to the block using a zipper

For conventional engine geometries of intake heads mated to cylinder blocks, the main limiting factor is not simply material strength, but clamping force, to stop gas leaks every time combustion events happen at higher peak pressure levels. Bolts are used because it is a simple part that is easy to service in a cramped engine bay and torque to spec.
Of course, if instead of using single cast block+head, you use individual monolithic cylinders like in radial engines, then there is no leaky seams or gaskets to worry about in the combustion chamber, and these can be fastened to the crank case by various means.

Why not velcro them instead? Worked for shoes, would work for cylinder heads too

we have the technology to not need pistons at all

We have the technology to make you stop sucking dicks yet here we are.

>>28511959 (OP)
Then machine it yourself, machinelet.

>>28513482
Do we though?

>>28513464
>modern electric motors are held together with magnets
hmm, why can't we hold cylinder heads with magnets too?

They should just make the head and block one cast unit.

>op didn't use a bunch of 1mm magnets to hold his cylinder heads to the block
>op doesn't use repurposed glue from post-it notes to attach his cylinder heads to the block
>op doesn't just tie a string around the block and cylinder head to hold them together
>op doesn't forego any method of attaching the cylinder head to the block and just let the vacuum generated by the intake stroke hold it in place long enough to last until the next intake stroke
Not gonna make it OP. Not gonna make it.

I want to talk about how terrible an idea this is, but honestly with cylinder heads failing far less than they ever have and most modern engines being considered disposable it has slight merit. I don't want to think about servicing valves though. Pull engine, flip over, remove crank, remove pistons, access valves, then reassemble.

>yeah I just had the heads resurfaced, had to take em down one half plate

>>28511959 (OP)
One of these has that as a thing
