wow .100 that would bring the compression up lol...
however i would have to mill the intake as well... and with mill i mean use a grinder lol
as you guys said.. i check the 360 heads condition ... see what spings are in it ( since the motor had a Comp cam ) and then if consider a MILL JOB probably arround.30 max for the intake fitment ...
IF the Guides are loose as they where on my 440 452 casting heads ( i didnt see that) i will not invest in the 360 heads. it will come out to 600-700$
my 452 heads with springs, valve job,milling new guides etc and done right are 650$
for 1200 i could have had SM heads which are regardless far superior.
