Why do i have 862 heads on my ls1?
I have an 01 trans am, i looked at my head casting numbers today and noticed that my passenger side head has 862, and the driver side has 864 as the last three.....i did a search on em an they say 5.3 heads....did some f-body's come with these or what?

but whats the deal with the 864 head? and from what ive looked up the 5.3 head flows very very close to the ls1 heads even with the smaller valves.
but as stated early id see if your block is iron or if you can get to any identifying numbers it may have had the motor pop in it and the previous owner dropped a 5.3 off in it

i just checked the block, the block is cast iron....where are the casting numbers located on 5.3 and 6.0's? the guys with the stock ls1 cant beat me so im hoping its a 6.0 block, and it does have the ls6 intake

I circled the block size location on the engine below so you can see where to look.
