Im in the market for new aluminum heads, because I want higher compression and more power. Basically Id like to get the max power you can out of this without stroking it. I kick myself for not making it a stroker when I had the chance. I had the motor rebuilt, AAANNND that would have been the time to stroke it...... The mechanics who rebuilt it urged me to put a 351 mild cam in it. I didnt know too much about it then and just wanted to get the car running. (I dont think it made much of a HP gain, Im chalking that up to folklore)But now I want to mess with it more of course, because cars r fun, ha. So its rebuilt, 351 "mild" cam bored .030" over new edlebrock 600 cfm carb edelbrock manifold. There is a really great article on line by Hot rod mag that tests 3 or 4 different heads, edelbrock e street series came in second, the first required some mods to the heads to make them go... https://www.hotrod.com/articles/ccrp-1302-six-budget-ford-heads-that-work/ It does note, that the high horse power was helped out a lot by the larger valves, that require more clearance on the piston head, not the stock ones... which they prob put in mine when rebuilt, another kick in the ass. Im seriously looking at the top end kits jegs offers as a package. Edlelbrock E street heads. or Edelbrock RPM power package... Im realizing there are a number of way and combos you can do here. Any tips? anybody have advise on the subject? If I buy the kit, it comes all in one package, but is there a silver bullet here? Can I swap the cam out with a lumpier cam for more power? Is it really a HP killer to go with the heads with the smaller valves? The larger ones are 2.02"/1.60" but require more clearance than on stock pistons. The smaller ones suggested for stock are just under that really... Or is there a combo of heads, intake and cam I should get?
