What are you guys with aftermarket sleeves using? Right now I have a GE sleeved h22 block and ge/oem cut head gasket. The bore is 89mm. I believe it is stepped deck already, but should I add o-rings or am i going to be ok? I plan to run as much boost as 92octane gas and a t3/t4 can support

 

Step decked GE sleeves here. Just make sure bith surfaces are flat, use some copper spray and torque the head bolts correctly.

how many psi are you running? From what I've heard, with higher psi 20+, you should use o-rings. Is that true?

 

What's wrong with doing a flat deck? Cometic makes a hi boost headgasket...

 

im not 100% sure but when i got my block back from GE with the o ring set up they told me not to use Cometic headgasket. I used OEM headgasket with o ring boostin at 15psi and 75 shot of nitrous

Haven't ran it yet but I will be boosting 28psi. There are quite a few people running step decks with no O-rings that have no problems. Do a quick search under my name and there is a post about this that I made. It will contain all your answers as it did for me
