I would stick with that block, but if you can afford it go with better heads because the stock heads are ok for MPG but not really a performance head.If you can't afford aftermarket heads , then you can go with a 351 W head (only the ones with 1.84 intake) , or go with 289-4v heads because they have smaller chambers and increase comp. ratio, one head alot of people forget about too is the 68 302-4v (has 53.5cc chambers) and these heads are fairly cheap and will also increase comp. ratio quite a bit.As far as your compression ratio , I don't have the exact specs for 74 (all I got is 73 and 75, sorry) but this should give you an idea, 73 8.5:1 , 75 8.0:1.Hope this helps
