M10x1.5 Accessory hole commonly used for dipstick is shallower than OEM to prevent water jacket intrusion, please check your dipstick bolt prior to final assembly. Like many aftermarket heads, a sealant will be required on intake rocker bolt threads that intersect the port. ALWAYS VERIFY NEVER ASSUME all engine clearances before final assembly. C5\/C6 Corvette alternator brackets WILL require minor clearancing to bolt flush to the engine. Due to the outer dimensions of most aftermarket cylinder head castings being slightly different than OEM, some bracket or manifold clearancing may be needed for some applications. Test fit all manifolds and brackets before installation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BRIAN TOOLEY","offers":[{"title":"Just one head \/ No Thank you","offer_id":48854065610984,"sku":null,"price":1595.0,"currency_code":"USD","in_stock":true},{"title":"Just one head \/ YES PLEASE!","offer_id":48854066594024,"sku":null,"price":1895.0,"currency_code":"USD","in_stock":true},{"title":"I need a Full Set (2heads) \/ No Thank you","offer_id":48854065643752,"sku":null,"price":3190.0,"currency_code":"USD","in_stock":true},{"title":"I need a Full Set (2heads) \/ YES PLEASE!","offer_id":48854066626792,"sku":null,"price":3490.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1919\/3325\/files\/btr-cvh1c-6ab_1.jpg?v=1785958441","url":"https:\/\/boostdistrict.com\/products\/btr-canted-valve-ls-cylinder-head-ls3-6-bolt-cnc-ported-btr-cvh3c-6a","provider":"BoostDistrict","version":"1.0","type":"link"}
