glad to help... onther good thing you should do anyway is to put a 180* t-stat in it. the stock heads are prone to cracking between the valve seats, doing the 180 t-stat helps IMO. also, you may have 2 cats right after your exhaust manifolds, make sure they flow good and do not plug up. they will take out your exhaust seats on the #8 & #7 cylinders if it goes to long... ask me how I know [&:]

 

will i have problems if i change it? i have heard that people run into tons of problems when they did... let me know cause im gonna change the heater core and it would be the profect time to do it

 

you shouldnt have any problems changing the t-stat.. it's easy. use a genuine mopar gasket on it and you dont even need sealant on it, the sealant is in the gasket.

 

thanks a ton...
