I guess that it is a 2lte 2.4

i have the 3l 2.8 head on my 2lte I LOVE IT have put over 100,000 kms on it i cruise 110- 120 km/h all day long with it <daily driver>
A lot of guys have gotten heads from Allhead in Australia with good results. Most everyone uses the 3L head on their 2LT-E. I've ordered parts for my 2LT-E (no head yet--knock on wood) from Castle Hill Toyota (in Australia) with great results. I understand that a new 2LT-E head with the valves and rack in it is around $1500US.
