need help with heads

[t&tkennels]

My '71 has a 350 2bl. from a 78-80 model passenger car. it has 1970126 heads & from what i understand they low performance , 76cc,1.72 int. valve heads. i think the stock compression is 8.0 or 8.5 . what i want to do is raise my compreesion up to 9.5-10.0. i found a set of heads for $400.00 with 65cc chambers & 2.02 & 1.60 valves with a 3 angle valve job. will these heads give me the compression i want.?other specs of the engine will be as follows, performer intake, 600 edelbrock, 279 comp cam thumpr, 1&5/8 headers & 2 and 1/2 exhuast. Thanks

Sounds like the right path. I have 64 cc Trick Flow 2.02. 10:1 compression. 290 duration Crane cams fireballII. Weind stealth intake, with a holley 650 going out 2.5.

The heads won't give you the compression. You need to swap your pistons out.

I think a .100 dome piston would put you in that compression range with those heads. You can cut the heads down a little to gain a better gasket mating surface while raising the compression slightly.

ok i went to comp cams web site, & they recomend 9.0:1 compression for this cam. will the heads at least give me that.? i really dont want to go into the bottem end of the engine ,cuz for one its in exellent shape & i really dont have the money to do so. but i really need to replace the heads cuz i know i cant make any power with the stockers, Thanks for any & all help.

that should get you close. You might want to look at a good used set of vortec heads. the standard 350 versions have 64ccs but you would need a vortec intake. I think the 305 versions have smaller chambers.

I agree X2.

Patriot was doing a special on their Vortec heads. They are a Patriot casting which allows you to run both a standard intake or Vortec as well as either perimiter or center bolt valve covers. For the money, they are a great head IMO..
