gprimm Posted October 17, 2012 Share Posted October 17, 2012 We are putting a rebuilt set up heads on my sons 78 Malibu Classic Wagon (don't worry guys, I built it three years ago and everything is changed). The reason we are changing is that the long block was rebuilt at a shop; the short block is fantastic, but the heads weren't rebuilt that great and are smoking after 5,000 miles. So brought in a low miles set of cast iron heads, had screw-in studs put in, some valve work, etc. The head guy suggested that since the Howard cam is mild, he suggests putting 1.6 ratio on the intake for a little more power. Thoughts? Quote Link to comment Share on other sites More sharing options...
CrazyDavey Posted October 17, 2012 Share Posted October 17, 2012 well that's kind of race car advice, it might show up on a time slip but you would never feel it on the street. You would also have to be careful you are not adversely affecting your piston to valve clearance..if it's just a fun street car I don't see any point to doing it..JMO....

71monteme Posted October 17, 2012 Share Posted October 17, 2012 ditto what davey said. also valve geometry might change. if so new push rods will be required. thanh Quote Link to comment Share on other sites More sharing options...
