4027596 318 head questions??? Help

'89 were the last RWD cars- Diplomat, Fury, and New Yorker Fifth Avenue. 318 only- 2bbl roller cam in civvy cars, 318 2bbl or 4bbl likely with flat tappet in police cars. '89 was first 360 TBIs, '92 was the first Magnums, '93 was the first Magnum 360s- '93 is also when the 318 Jeep Grand Cherokee came out.

The 714 is a roller 318 head? Interesting to accuse any 318 head of being the best LA head with their small ports and thin castings with small stock valves. The 308 open chamber TBI 360 head sometimes is accused of that.

4027596 is I'm pretty sure a 318 4bbl/360 smog head with 1.88/1.60 valves and large ports.
