If you look up part # on 92 Marquis and 95 Mustang at autozone, they list the same part #.
Ok sorry for mis reading you.
I feel like if I'm gonna start getting into head changes, it's crate motor time.
Not ready for that......... Yet.
Gonna go with the list I posted in this thread and see how I like it.
Stick with the bolt ons. Exhaust, pulleys,and, and an e-fan. Save the intake for later. If pulling heads seems daunting the intake isn't much easier and with the lower intake off the heads only have 8 more bolts holding them down.
It's not that changing the heads is daunting. Ive rebuilt and ported heads in the past. My problem is that if I go that far, I just keep going. Like I said, stroker crate motor time.
I admit that what you say makes sense. But I still believe the combo of things I have planned will work good for some noticeable gains if tuned right.
