Head Help

We could go round and round (like we usually do ;-) but again, all parts/sub-assemblies/work considered need to be thought out before going forward. Duster, what rear end gears, convertor and tire size are you running? What RPMs do you plan on turning? When you say street/strip, I am going to assume that it is mainly street with a little strip use. Since you are trying to use the original rotating assembly, I am thinking you are on a budget (like many of us) so is port work (especially full port work) realistic at this time?

Also, this is a 340 but for some reason (maybe something I read in another one of your posts), I am thinking that this is a '73 340 (correct me if I wrong). If correct, consider two things. First, you are running a cast crank (which is fine for a healthy street build) and secondly and most importantly, your compression (again, with using the stock rotating assembly) is probably not going to support what you plan on doing with this. If this is not a low compression '72-'73 motor, then disregard the majority of this paragraph. Anyway, there are questions on suspension as well but let's leave it here for now. I know that your father and older brother are also on here and I know that will help vs if you were just doing this by yourself.
