Head cast #

[notnearlow]

Within the next month or so i will be doing a rebuild on my motor. I went outside today and got the cast numbers off of my motor. I am just curious if my heads are a desirable or if i should go look in the junk yard for a set with better numbers. The heads have a cast number of 330545 and the block has a number of 3970010. Any info will be helpful

Thank you. I see the numbers but are these "good" heads or just average?

Just standard big valve heads. Nothing special.

Thats what i figured. Thank you for the help.

They are actually kind of desirable because they are heavy casting heads, and they have 2.02/1.60 valves. That being said, a set of Vortecs with smaller valves will still be head and shoulders better than those heads.
