I have a set of 502 aluminum heads, 2.19/1.88 stainless valves, 290cc runners, 110cc chambers that look to be a set of crate engine pull offs. They look to have never been run. It is just the heads and valves, no springs or rocker hardware. Asking $1200 OBO. Heads are $700 bare new from Chevy. Call or text Jonathan at 903 293 0188 for pics.

 

any info on part numbers, and do they fit an 8.1l

 

Here's the part number from GM's website


12363392 Bow Tie Performance 12363391 Aluminum A356-T6 Semi-open 110cc I: 2.19"
E: 1.88" 290 Oval Square Head includes springs and valves.

And from what I've been able to research, they don't fit the 8.1's, they are for the older mark4 through gen6 blocks.
