the casting number on my chevy heads
is 14102196

The last number isdefenately a 6
on the sideof the heads ther is 2 slash marks


I am haveing problems identifing
what engine they came from and what
diameter the valves are.

the block was cast in canada in 1987

On the side of the block ther is a
glued on tag whith the numbers
940201437 stamped on it.

I dont know if the block and heads are from the
same engine/

could this be a waranty engine?

I checked a few websites and cant find
out any info...

THANKS

I didn't find your exact casting # here - http://www.mortec.com/castnum.htm

But it should be '87+ 350 heads.
