I have a 1987 dodge dakota 3.9 6 cylinder does anybody know if it's interference or non interference

 

A lot of people say it's an interference engine but I've seen several pop chains and a new timing set got it going again. I believe there are valve reliefs in the head of the piston. Your engine is a 318 with 2 cylinder removed. It's a one off year as the '86 was a slant 6 motor and the '88 was a fuel injected engine with roller lifters.
