well i blew a HG last night, hope i didnt warp the head but i wont be able to find out until how bad for 2 weeks until i get back from vacation. just to get things started, after i replace the HG should i do a retorque on the head bolts? if so after how many heat cycles? it is leaking external and dripping down the block. o well did it once, like my buddy said practise makes perfect.
