340 heads on 360?

The post is about 340 and 360 heads, not those 302 door stops
Fair enough as to the OP's question, but We pretty much covered that up front. That's not the way CB worded it in His post, and the OP, having little to no experience may
not know the 302 & subsequent versions exist. Whether or not He is ever going to use them, it is simply information, no need for someone to take it personally..............
As far as doorstops,....lol!
