10.5:1 CR Goal with Hyundai Head

[lasthope05]

These Sonata heads are based off a 2G design, but have smaller ports than even the 2G.



I would suggest one or the other yes. Dave W. was using a 1.6 small combustion chamber head at one point discovered that the head was a thinner casting. He was having gasket issues a lot.

The 2G head is going to be by far the superior head all the way around. I wouldn't get to hung up on the combustion size for our engines and trying to get at that 10.5:1. Get a thinner gasket and some high comp pistons and you should be close.

Is there a thread about the thinner casting and how he came up with that?

The two heads with 43cc volume are the 1.6l 4g61/g4cr(2g style ports) 1.8 4g67/g4cn(1g ports).

I have a spare 1.8 head sitting around and don't really see much differences besides the smaller shrouded combustion cambers.

No thread on it. Just a personal experience with the two.
