I am looking to go with stock heads with a T-Rex. What castings should I look for though? Bottoem end will be forged.
Thanks.

All ls1 heads are the same? I just want the best flowing that a T-Rex will fit under with stock head gaskets. Anyone?

Get a set of 243 LS6 heads if your staying stock.
Also if the bottom end is done and you have 2cc valve relives, mill the heads 50-60 thousands and get that compression up.

Where do you get the stock LS6 heads from?

I'd get the PRC stg 1 243 heads. They are only $999 outright.

243 un-milled heads would be the best route.

Would the 5.3 heads fit ok with a T-Rex?

If your going through the bottom end why wouldnt you reuse the heads you have now?

Not going through the bottom end. I am buying a whole new forged shortblock. Old one blew up! Sold my old STG 2 heads and now I have to start from scratch. Just want something cheap that will work good with a T-Rex, and dont want to mess with PTVC problems.

241's are cheap (2000-2002) check the for sale section ebay is a rip off.

Are 853's the worse or 5.3 heads?

Whats the real difference in the 853's, 241's, 243's, 5.3's anyways?
