Re: best bbc cast heads
I don't think the 396 came with 781s or 049s......if you have to run correct casting number heads you will probably have to run the closed chamber ovals for a 325 hp application.
To add to this, I am building a 68 or 69 camaro to race in NHRA stock and super stock eliminator, using a 396/325 or 396/350 most likely. For those years, as per the NHRA tech bulletins that were supplied by the OEMs back then, the accepted cylinder heads for '68 and '69 were heads with casting numbers ending in 215, 063, 290, and I think one more but can't recall now.
I called Dave Layer of Heads Up cylinder heads and asked him about the flow rates on these heads and which ones were the best choice.....he told me they have done lots of 063s and that there was something a little funky with the 215s.
That conversation was in regards to a super stock application which allows porting and epoxying of the runners as long as factory CC is maintained. For a stock application, where the heads have to be untouched, I would recommend calling people like Steve Koppien in North Dakota, Parsons and Myers racing engines, Bub Whitaker of Burtonsville Performance and Machine in Maryland, Warren Racing Engines in Clinton NC, and perhaps a few others that have considerable experience (and national records) with these applications.
I hope this helps!
