Don't know too* much about engines but can someone tell me what heads you use when building a 408, can you use the 360 heads? Or do they have to be ported? Thanks
You would be much better off asking your question in a new thread that is your own thread. Things get confusing when multiple questions are asked in one thread. Start your own thread and I'll input what I know. I'm not an expert but have had a fair amount of experience
