Thanks for the response..kinda on the fence here..if I do pass on them will def give you all the chance to make your own deal on them...prob need to stay with the 440 plan since I have everything already except some flycutting on my pistons...but I would like to oneday have a 451 set-up have seen several seem to run out pretty good and stay together that were properly done....I got til the weekend to make up my senile mind....whats their value in reality,may trade for them and pass them on...not looking to make money here or profit just wonder how much should invest in trading parts...
