it is all a big miss match pile of parts were do you want to start ? all studs towers on GM alum heads can fail many have been fixed old heads Race head that have been ran hard many times .old heads ... old news.i have fix them .if there not crack or busted that,s good . but if so may be better to sell them and buy a new head that ,s up to speed for port size and flow . cam is not right for the CR you have . you will need lot of gear and stall to make it work. for the street . that intake works good.i have used them but not that good for the small engine for street .bump up the CR two points+ . deal with the hi stall and gear = Hi RPM . low speed idle around town with that cam could be less then great . headers could be bigger.i used cams like this for short run street cars they are fine for 10to 20 mile trips but you need better then 12to1 .lower RPM can be soggy you will have to be in the power band of that cam all the time under the cam it will be not much fun and you will be there most of the time on the street
