Wanted to see how much HP and Boost people have run on the OEM sleeves. Have heard of alot of people using the aftermarket sleeves like Golden Eagle or Darton sleeves.

Since I want to use the OEM sleeves can I still use the factory headgasket.
I think that for high boost you need either a o-ringed block or
o-ringed headgaket like the cometic HP gasket.

Not too much known on this topic thanks for the info

The stock sleeves should work up to like 450+hp (20+psi depending on setup), but if the motor detonates any it will most likely split the sleeve. I have personally seen low 400's but I am sure people have made well over 550hp. The stock head gasket should be fine with ARP head studs without any O ring or O ringed headgasket. Headgasket problems are usually caused from improper tuning. IMO

i have witnessed over 600 on the dyno... so i know it possible

 

sure is

 

it's possible, but the slightest amount of detonation and they're gone!!

 

Well if the sleeve cracks due to too much boost or detonation will that damage the internal engine components or just need to be re-sleeved and re-ringed?
I have brand new 81 mm pistons I wanted to use these until the sleeve give out then get the aftermarket sleeves in the long run.
