How can you tell the difference between LT1 and LT4 heads?
 

I'm looking around for some LT4 heads and if I buy some used I want to be able to tell the difference so I don't get screwed.

hmm. i dont know if u actually can, i think there internas are just different, but i may be wrong

the casting numbers will tell just don't ask me what they are

and the obvious fact that its powdercoated red.

ah crap my bad. lol. thats the intake.
