Murphy Posted May 24, 2012 Share Posted May 24, 2012 Anyone have info on these SBC heads #3890468? They have the double humps but I can't seem to find this casting number on any website?? Quote Link to comment Share on other sites More sharing options...
Wiham Posted May 24, 2012 Share Posted May 24, 2012 Could the last number be a 2, not an 8? If so, they're: 302/327/350 62-68 1.94/1.50 OR 2.02/1.60 64cc Double humps Quote Link to comment Share on other sites More sharing options...
Murphy Posted May 24, 2012 Author Share Posted May 24, 2012 I just texted the guy to question his numbers and sure enough he fat fingered the part #.........they are 462's. Is there any other code to determine whether they are 2.02 or 1.94's?? Quote Link to comment Share on other sites More sharing options...
Wiham Posted May 24, 2012 Share Posted May 24, 2012 Not that I know of, probably have to break out the calipers and measure. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted May 25, 2012 Share Posted May 25, 2012 if you plan on using them on your Monte, please be aware of the fact that the heads do not have accessory bolt holes. Quote Link to comment Share on other sites More sharing options...
