Eddy head question
The imm rhs heads go for around 1500'ish
$ound$ like you really want the eddy head$, nothing said will $way you...so in that ca$e....$pend the 1400+$hipping, then take them to a $hop and pay around 400 dollar$ for the corrective work and $pring $et up.... and then another 400 dollar$ 'optional' to have them bowl blended $o that they actually flow 250-260's cfm 'might a$ well make this worth while' and then buy a new cam that will lift the valve into the .550-.600 lift range where tho$ eddy$ flow good, otherwi$e you'll more than likely only net about 240cfm with the .500 or le$$ lift $treet cam$ offered/typically u$ed.
good luck.
