ok so I mis enterpreted (sp?) what was written sorry for the confusion (and sorry for bein rude 66) so I should try and trade off my 72s for 73 to ? (need to find production years) 400 heads and rebuild them using Kbs and if I had the heads that came origanally with it I would use them but I don't also I ran across something the other day and it interested me the stock compression for a 70 440 was 9:7.1 with a pair of smog heads that run on unleaded that make the same comp. Could I run that compression ratio on the street or is the cut off 9:5.1 if so I may just fubar the 400 and go with a 440 hell I don't know I need to decide quick though the last thing I need is my mom getting po'ed because im not getting it running once again thanx for all the help
