With Die Cutting the finished edges are also far superior, leaving a much smoother, neater edge to the gasket as opposed to laser cut steel which leaves a sharper edge behind.\u003c\/p\u003e\n\u003cp\u003eFor the ultimate seal all our gaskets are manufactured and designed to accept the larger 12mm and 14mm cylinder head studs also available from our online store. The standard cylinder head bolt (the component that joins the cylinder head to the block and offers force to seal your cylinder head gasket in place) is 11mm thick and uses a relatively fine thread. It is important to remember this bolt was developed for use on a mainstream engine producing no more than 320Bhp, Subaru did not manufacture this bolt for use with anything above this power and as such it is important to consider stronger and more suitable replacements.\u003c\/p\u003e\n\u003cp\u003eHere at RCM we manufacture both a 12mm and 14mm replacement head stud and nut kits. The studs are naturally stronger due to their extra thickness and superior material quality but they also benefit from a much coarser rolled thread (meaning you can tighten them far more than the standard bolt which in turn will offer a much higher clamping load between both the cylinder head and block faces where you head gasket is situated.)\u003c\/p\u003e\n\u003cp\u003eReliability is key to any engine rebuild, whether done for higher horsepower applications or just a simple repair \/ refresh it's important to choose your components wisely so that you don’t end up repeating the process later down the line.\u003c\/p\u003e\n\u003cp\u003eGaskets are priced individually. You will need to purchase x2 gaskets for a Subaru engine build.\u003c\/p\u003e","brand":"RCM","offers":[{"title":"0.78mm \/ x2 Gaskets","offer_id":47736411160920,"sku":"RCM1683-2","price":166.67,"currency_code":"EUR","in_stock":true},{"title":"1.1mm \/ x2 Gaskets","offer_id":47736411226456,"sku":"RCM1684-2","price":166.67,"currency_code":"EUR","in_stock":true},{"title":"1.5mm \/ x2 Gaskets","offer_id":47736411291992,"sku":"RCM1685-2","price":166.67,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0146\/4575\/6004\/products\/5a1ab9a50a.jpg?v=1752661052"},{"product_id":"supertech-audi-vw-1-8t-5v-inconel-exhaust-valve-set-of-12","title":"Supertech Audi\/VW 1.8T 5V Inconel Exhaust Valve - Set of 12 AEVI-1103-12","description":"\u003cp\u003eSupertech Audi\/VW 1.8T 5V Inconel Exhaust Valve - Set of 12\u003c\/p\u003e\n\n\u003cp\u003eSKU: AEVI-1103-12\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":47862361227608,"sku":"SPTAEVI-1103-12","price":412.34,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0146\/4575\/6004\/products\/70c69f46956d571b59f06202dd4487c1.jpg?v=1752660648"},{"product_id":"supertech-audi-vw-1-8t-5v-inconel-exhaust-valve-set-of-9","title":"Supertech Audi\/VW 1.8T 5V Inconel Exhaust Valve - Set of 8 AEVI-1103S-8","description":"\u003cp\u003eSupertech Audi\/VW 1.8T 5V Inconel Exhaust Valve - Set of 8\u003c\/p\u003e\n\n\u003cp\u003eSKU: AEVI-1103S-8\u003c\/p\u003e","brand":"Supertech","offers":[{"title":"Default Title","offer_id":47862361620824,"sku":"SPTAEVI-1103S-8","price":274.91,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0146\/4575\/6004\/products\/e78c82a1b6c8a0af90ff303297371b9c_3bd72fe8-04b1-465b-968d-8ff17b443525.png?v=1752660648"}],"url":"https:\/\/www.marseal-motors.com\/en-de\/collections\/zylinderkopf.oembed?page=33","provider":"Marseal Motors","version":"1.0","type":"link"}
