318 cylinderheads

[joshua dewitt]

have 1973 318 stck cylinder heads, running .30 pistion 9.0:1 340 purple cam, mopar performance thin head gaskets. torqer intake, 625 or 650 carb.. can't remember... headers and performance exhaust...
would these heads with the eldebrock rpm valve springs i have do well? or should i look for 302 castings... would love alumn. heads but out of the budget right now. was planning on doing a little port work ( home pocket port) on them... 360 heads arn't worth the money people want for them out hear pluss would lower my compression alot. mainly a street car with a little fun factor,, can allways upgrade if needed. just looking for some insight...

Joshua, from what I see here, throw a set of Comp #901-16 or Crane #99835 springs on the original heads

and at some point, swap out the Torker for a Eddy Performer, and enjoy what you have.



P.S. if you do use Eddy springs. The #5777 is the one to use for a replacement @1.65" installed height. The one's that come with their heads have a 1.80" installed height and would probably throw more seat pressure to it then you really need.

Josh, try degreeing the cam in, 1st checking where its at now.
Like Rick said, go with performer intake if the heads stay on.

Now if you port the heads you may as well open the windows up to a 360 gasket and bolt a LD340/RPM/AIRGAP intake on.
