H-350 cylinder head help

Nick from MD · Oct 30, 2014

Can anyone tell me if the combustion chamber is the same on a head with the casting number 361479r1 and head with the number 362533r1? Also what is the casting number on the LP heads? Thanks Nick.

. I would be more concerned about port volume, valve size, flow and if there is a quench area.

If you run across a kerosene head the combustion chambers are much deeper. You can see the difference. Other heads are close enough that you don't need to remember the casting numbers. The only real good way to raise your compression is with different pistons.

They are shaped the same. May not CC exact but should be close. 362533R1 has part of the combustion chamber edge sloped off on one side like the 8043 DD and the 361479R1 heads. 8043 DC and lower have a squared edge.
364017 is LP.

What ever head you end up using. It should have a flat quench area that the piston approaches to within 30-40 thou cold. This improves combustion chamber turbulence, improves air/fuel mixing and reduces the tendency to knock.
