Heads
I have a TFS1 cam, and a Trick Flow Track Heat intake. I have a set of TFS TW heads on the engine now, but I dont know which heads(specifically) they are (bought a car that had them on it). The heads were slightly damaged a bit so I was just going to sell the set and buy a new set (I have other reasons for wanting to sell and buy new, so bear with me, I dont want to get them fixed or what not). I was looking around on summit, and I guess Trick Flow decided to name every set of heads they make "Twisted Wedge". There are a bunch of different part numbers, and generally the differences are Combustion Chamber volume (61,64,65cc) and intake/exhaust runner volume (forgot the sizes). Looks like the bigger the Combustion Chamber, the bigger the runner volume. Now, since I want to buy a new set, which set would be best for a stock bottom end with a TFS1 cam and Track Heat intake? I know this seems like a dumb question, but there are some part numbers on Summit that are different(price different too), but I cant find the difference in the description. I was thinking that since it is basically a stock 302 with a cam and intake, that the 61cc combustion chamber and 170cc Intake/66cc Exhaust would be best, but some insight maybe? Since its just a TFS1 cam, it only needs single valve springs right? Would it possibly be better in trying to do an AFR 165 or AFR 185 head? Opinions please? Thank you.
