Hi lads I'm after a bit of help iv got problems with my 3dr Cosworth YB motor and its got to come out . So wot I'm thinking of doing is starting work on a second hand block witch is on standerd size which is a plus but there is a but with it this replacement block has been wire rung . Wot I'm asking for help is do I use the wire rings and use a standerd head gasket or do I just forget the ring and fit a standerd head gasket . Or do I have the block decked till the rings are gone so I can use a multi layer gasket and flash the tops of the pistons which is not a problem . I need this to be good for 400BHP thanks for your time

Wire ring it and use a small turbo head gasket

Multi later requires head and block to be perfect = more expense

Oh and std head bolts too

my last saph was built by a previous employee of nms, the car ran proper rs500 t4 at 2.2 bar 480 hp and all it had was a multi layer head gasket and standard head bolts and i never had any headgasket issues.

I run 2.5 on a 611 head gasket

Mat another thing to consider and also check are the head bolt length. as heads are skimmed the bolts go into the block deeper the rear 2 its not a problem but if any of the others bottom out it will crack the block on number 2 exhaust side as thats a weak point of the 2wd block. and the gasket wont be clamped correctly hence why theres a lot of issues with failing gaskets.

Hope this helps
