lemme repeat, hughes "IRON RAMS"

flow 95% of an eddie head for less than 5/8 the cost, come assembled with hughes 1110 springs (120lb seat, 300lb@.5" lift, 360 lb/in rate).


here's from hughes website (I cropped so they're side by side):



nice apples to apples comparison since these are all done at the same shop on the same bench. the 1.92" valve enginequest heads flow nearly identical to the eddies until .5" where they give up 10cfm. X heads would flow pretty much the same as the '576 heads in the chart.


using stock mag rockers would up the lift on your cam to .509/512" lift.

stock magnum rockers are $9.69/cyl from rockauto.com, or you can use any aftermarket chevy/amc roller rocker...scorpion performace rollers (made in florida) are $200-250 for amc apps on ebay

order the 318B's, LA intake bolts up, LA valve covers & headers bolt right up to mag heads too.

if the MP 7.625" conversion pushrods are too short (has been the case for some people), summit sells 7.65" pushrods for $63.

the comp lifters are amc style with pushrod oiling provisions, so your total cost (using OEM rockers) is about $950....or less than $1100 using some pretty nice roller rockers.
