Heads for 440

You can not look at a video and make a decision on how long your pushrods need to be, you need an adjustable pushrod tool to check YOURS. So after you actually get the heads that you buy on, then you will check yours. Also, any aluminum head is going to be lighter than steel and cool better.
I know that, what i was saying is, i have always used stock stuff so measuring for a certain length pushrod will be new to me, so i got to looking for videos explaining how to do it and i could only find the video where he is using roller rockers..I didnt plan on using roller rockers so was saying i dont know how to set up and measure with regular rockers as regular rockers dont have the roller that would roll on the marked surface of the valve stem to see where it hits..
