New Head bolt kit for Ecotec (series II & III) engines
Owner: SicSix
We are rebuilding our 231 (3.8 ltr) engine, end of 2012 year we had a head gasket failure and this damaged the deck surface, at the time this engine was running at 24 psi and doing 10.8 @ 129,9 mph, We looked at how to improve our clamping force, with the help of ARP we had new stud kits made, they are now 1/2" and we build a engine up with the new stud kit, we can now do our nuts up to 110 instead of 80 ft.lbs that is approx 40% more.
This modification is only for engines that run more then 25 psi, the MLS gaskets can be machined to take the new 1/2" studs and to drill out the heads we did not encounter any problems with the water jackets, ( all machining was done on a milling machine) the nuts on the exhaust side are a bid difficult to put a socket on this was fixed by machining the socket back.
We have some of the stud kits in stock at this time.
