OK i can't k line now ? so it guides made up now . that's a extra $160 so that's $610 on heads now . i'll use the cam that i have with my 1.6 rockers that will make in .545" / ex .542" lift & with that duration @ .050" that's pretty good for now , it will get my heads working . ( I'm hoping the 2 3/4 inch carb spacer will pick up some air speed to make the larger ports & valves & cam work together ) with that 107 lobe separation , when the power comes on i should know all about it . ( i have never seen how it goes because of the timing & tuning problems )
my ute ran 13.6 @ 100 miles per hour the night be for we pulled her down .
without carb spacer .. i put that on & cut a hole in the bonnet 2 1/2 hours before we pulled her down . it definitely felt like it was pulling harder mid to top .

heads finished
the heads are quite wild now . i would say there max wedge or bigger now . hey they could go backwards for all i know but i doubt it . so to make the most of it , i 'm gonna buy a new stroker crank from 440 source / or muscle motors . a 440 stroke / b mains , a friend is giving me his ly rods to use .
if my heads crack once they get some heat into them i can always use my Indy's . & if i use my Indy's i'll change my rods & cam as well .
I'm also getting diamond forged dome tops . i'll have to do something about my 727 now , maybe a bolt in sprag & Kevlar bands & better friction & steel plates . just keep throwing buckets of at it .
