AFR vs ETP vs RHS Heads
Currently i have AFR 205cc 62cc heads but im wondering if i made the right choice as far as MAX TQ is what im looking for cuz i could care less for high end i want the fastest 1/4mile car (dont we all) but here's what i saw with all three and tell me what you think...
PS in the future im stroking to a 408 so if i did higher CC now like 225cc or 235cc will it hurt me alot at my 346 na stage??
AFR 205cc Mongoose LS1 Heads 62cc $2095 bare
ET Performance LS1 CNC 215cc Runner 62cc $2250 bare
RHS Pro Elite Gen III LS1 210cc 62cc $2800 bare
Note: I am aware that each runner is slightly larger/smaller then one another but when taking into consideration flow-horsepower-torque which will be the best?
My overall opinion is the AFR will still be the TQ champs and the ET's over the RHS due to the price but just wanna see how everyone else thinks!

You need to determine how the heads work with your cam. You want to increase your SCR and DCR. The DCR is important, you want to get it to about 8.5 to 8.75 for 92-93 Octane keeping in mind that you want to minimize quench (thinner head gasket)
BTW - common knowlege is that AFR 205 rock up to 383 ci
225 if going bigger

Well from the setup i hav e now the cam works well with the heads... With the 62cc chambers it keeps the low end and the cam is lots of mid range and alil low end plus the 3" true dual helps with the low end also so all in all its all working together but i think the flow from the RHS heads might be better for my stock CI but when i go to a 408 stroker then i think def the 225cc AFRs but what do you think if i were to throw them on now instead of waiting till later?? Waste of money right cuz too much flow for too little cubes...
