these heads have less than 1200 miles on them. the heads were gasket matched and have b hive comp springs 550 lift. i ran this with my b cam and 1.7's ran a best 12.60. the heads specs are on the brodix website and are 7/16 studs. not 2.02 intake valve the 1.94's email me at jarmbrewster@yahoo.com with any questions. my car is still together and will be off by next weekend or sooner if they sell faster. i would prefer not to ship these heads but I would like $800 for them. not junk
