I have a gsr block on a type R head, high compression CTR PCT pistons 82mm bore with ls stroker, skunk 2 stage 2 tuner series camshafts, 440cc injectors 70mm throttle body running on e85 making 182whp and 125tq.

before this i thought i had blown the head gasket because oil was leaking pretty bad so i took the head apart for cleaning, new valve seals for the head and got a new head gasket.. as i got the motor back together i torqued the head down to 65ft/lbs
but a guy that i just met recently said that i might be having some power loss somewhere in my motor due to the power being so low .. he said i should torque the head down to 80ft/lbs for better sealing and power.

btw he claimed that he had built a LS vtec motor making at least 200whp with similar parts but on 91 pump gas w/81mm bore

right now the motor is running fine as it is and rev's to 8200 rpm..
anyone think i can bring the rev's up to 9000-94000 rpm safely with 65ft/lbs already or should i re torque the head then take the rev's up for more power?

 

Are you leaking oil?

 

no not at all at the moment

 

Then you should be fine. If the head was lifting at high RPM's you should have oil leak.

 

takes alot o boost to lift a head...and this is N/A...oem bolts are not reusable....if you have arp depends on what u used as a lube....oil vs arp lube will require different torque specs...65lbs is good for oem bolts in 3 steps 20-40-65lbs, arps u can do 20-40-70 depending on lube..
