i think he was just sayin that because his guy told him roller rockers where something he didnt need
maybe idk
but i would deffinitely get electric fans, electric water pump 35gpm or more, u could run mechanical feul pump but make sure its a good one, i would blcok it off and fo electric, jmo, and yes i would use roller rockers, its deffinitely worth the gains in hp they can give over stamped or roller tipped
