To do all that yo must be made of money.

Are the hardened exhaust seats really all that necessary for a street car?

I was lucky enough to have chosen to stay with my 351 cleveland, for this respect, cause did you know that the BBC (big block chev) roler rockers are the exact same dimentions as the 351C stock rockers. Of vourse they're slightly different, as the always are, 1.7's instead of 1.73 stock ration, but that's ok cause I got a new cam any ways, Ah how that 228/240 @ 50 and .535 lift sounds with 2.19 and 1.71 valves ( in the 2v heads of couse to achieve higher portvelocity).

Anyways sorry I'm not all that much help cause the tipical small block stuff, ie 289, 302, 351 are different dimentions in the valve train, I'm just so pleased with my new combination. Can't wait for this now in Canada to melt so I ca lay down a healthy number.
