Hyundai head
 

Ok so after a lot of research I haven't really found a good answer. I have a 1.8l Hyundai head which I believe is 43cc. I am planning to build a 6 bolt with 2g pistons which will raise compression. Would the Hyundai head bring the compression ratio up too high? Has any one done this combo? Or do I play it safe and just keep going with the 2g head?

You can use this head, the compression will be higher with the Hyundai head, but nothing scary.
