due to the previous owner taking my dx/hf hybrid motor to 8.5k on the tach several times daily, i about guarantee my head's got some issues that need 'straightened' out :lol: lol. how much should i shave though? .0020? .0030? it'll be a 1g hf head on a 1g dx block.

Take just enough to true upthe head... if you just take a little bit there may be some left to re grind if something ever happens in the future.

Most machine shops know how much to "shave" to make a head straight.
OR....My machine shop here in MICH. bolts the head to a absolutely straight steel plate and heats the head and cools it to straighten.Aluminum only of course. :wink:

it really suprises me that people do this kind of thing.

was the previous owner 16 or did he/she have something to prove? either way, "its made of metal, its not gonna break!", must have been going through their heads.
