it could very well be. He pm'ed me and said they were squeezing 28lbs of boost thru the small block.."alot of boost" from a ROOTS type blower..so i WOULD NOT doubt if it was caused from a cylinder blowing by......when you start packing that much boost in a motor..its gonna come out someone where.....which could lead into other problem areas like type of cam shaft and exhaust..if the boost is not getting out thru the exhaust valves (lobe seperation)into the exhauts pipes as fast as it is being put in,,you could squeeze out a gasket....,,,also there must be a good block invloved...LOL....
i am curious as to wht type of exhaust is on the car and what is the cam profile ?
He did order the hylomar...i had a 383 SBC with o-ringed block with SCE Copper head gaskets with a BDS stage 4 competition blower making 22lbs of boost and never passed any water..i did use the Blue brusg type haylo mar on both sides of the head gasket...but now keep in mind he is packing in 5 to7 more lbs of boost then i did also....i also ran Zoomie headers 2-1/4 primaries ( had to use adapter plates) and a very agreesive blower cam...
