hi guys, i know wat ur all thinking not another thread on this engine. Anyway ive done research on the engine and such and in the threads there seems to be no information concerning which 2tg head is best to use for the hybrid. more than likely this is becuase there hasnt been an engine built using all the different heads. anyway which 2tg head would be best to use theoredically that is? im thinking that it wouldnt make a difference.
well heres info on wat i will be using, a 3t-c block, mild cams (not sure totally as yet), last version 2t-geu efi, megasquirt comp, t-50 gearbox. im just wondering which head u would think would be best, cause im gonna b looking at an engine 2morow.
thanks

Pheonix,
I assume you are building a Naturally aspirated engine.
That being the case the 88222 - 88262 heads all use the same valves. The 88262 head tho was subjected to high emissions regulations and has an offset combustion chamber greatly reducinbg the amount of compression possible and your piston choices.
The 88260 and 88261 heads were generally EFI. The later is supposed to be slightly stronger due to an increase in the head webbing. Either the 88261 or 88260 head will be fine tho.
Earlyrolla,
I am not aware of any differences in combustion chamber between the 88222 and the 22260 or 88261 ? BUT I haven't looked either. I own both heads tho so if your curious I can grab em both so we can have a look. The 88262 on the other hand is VERY different.
If anyone has one of these heads (the 88262 head has no number on the casting) I wouldn't mind getting my hands on one so I can check a few things out.

Have a read:

thetoyman75 would be a better to answer the cam one.
From what I have read, the 88222 head have the better cam profile. So maybe a combination on 88222 cams and the 88260 head? If you have the money, why not have the cams reground specifically to suit your engine. I assume Wa is somewhere here in Western Australia? I have been recommended these guys:

for cam work. I haven't got to that stage yet though.
Shouldnt cost much for the thermostat housing and dizzy.
Guess, $40 for housing, $100 for dizzy...
