Head Choices - With Domed Pistons

Depends on what you want for compression. I start with that piston, set the chamber size, determine head gasket thickness I can get and then see how far out of the deck the piston deck needs to be. That’s usually ~.040-.050 out of the hole.

Once you do all that, you mock up the number one cylinder and do you half inch down fill. Calculate what you have for compression ratio and if it’s higher than you want you mill the dome down to get what you want.

Sounds difficult but it’s pretty simple really. The less dome you need to use the better. The piston is lighter. Dome height isn’t really an issue with the plug location where it is, but less dome is always better.
