but my question is would the 50cc combustion chambered 235cc version work? or would that raise the compression to much? or would i have to change the pistons? if so since my rotating assembly is already balanced would i be better off getting bigger combustion chambers? with the bigger combustion chambers would the heads flow as good? i have a set of the old dart pro 1 230's but want to get a better head if this is the eq head is not the best option to accomplish this any suggestions we be greatly appreciated. i have just came gfn i have already seen some information packed writings you and dave rock!! any help the two of you could give me would be great keep up the good work.
sorry to write so many questions but also i have a stock suspension buick regal this motor is going in and th400 tranny,coan converter 5000 stahl,it has a 8.5 grand national rear end with a posi unit 4.56 gear and 28 by 13.50 quick time pro tire, hoping to get the car down to 3100# could you recommend a cam for the eq heads? if you don't recommend these heads for me. how about if i have the pro 1's ported? what cam would you recommend? i know this is a lot of ?, but if you could help m,e out i would appreciate it every cam place recommends something way diffrent from the next it's frustrating, and picking a head is tough the eq's sound innovative if i was togo with them would they bennefit from a 2.10 intake valve. so if you can point me in the right direction for the best 23* head and cam.
it would be a big help thanks

Those Dart heads are probably 64ish cc which would put you at a ridiculous compression. The 50cc chamber is definitely more advanced in the flame propagation department, mostly it makes it easy to get a flat top in a 350 not so much a problem with a 400. Funny you should mention that motor as I have a 400 and I'm building a very similar engine. I can't recommend a cam for you not comfortable enough with that yet especially once you throw lots of compression and big inches into the equation.
