Like it says, looking for 340 or 360 Iron heads. I have a 318 but want some more airflow. I currently have a RPM intake ready to go on, just need the larger ported heads.
Excellent. I was told you have to open the top of the cylinder wall on 318s to use x heads to clear valves when the engine is hot. That would be great if they were bolt on.
Hi,i have several sets pm me mark
Thanks for the info. I thought X and J heads had same size valves.The X heads are the 2.02 intakes. You have to notch the cylinders for those to fit a 318. The J heads have the smaller intakes and will bolt to a 318 no problem.
