Trying to find out if I could put 340292 heads on my Tbi 350 motor. I do not know. what cam I have in it but I know the cylinder ports mic at 4.018 and which if I'm correct means they've been bored. The reason I'm asking is because as I was doing the tear down to replace head gasket my buddy showed up and had these already machined 292 heads. And of course if I can get rid of these junk 193 heads with the swap that would be great any information would be appreciated and if I did something wrong on the form I apologize
