Help Please - How-to remove oil filter mounting plate??

right on, i actually thought what u had were headmans, but now i see the hooker tag thats spot welded of the drivers side.

Im running the headman cheap'os on my 410, solid roller, ported heads, 10.1 comp....i know im giving up a lil top end, but it's gonna make enough power to where i could really care less. 800 dollars can do a lot of other things i need to do....like if someone were to say 'either 950 carb for 800 or tti's for 800.....ill take the carb. random thoughts..lol
