Ls2 cam selection help

[Mike Norris]

When it comes to cylinder heads, I always say you get what you pay for. For aftermarket heads I prefer AFR and Trickflow in that order. The downside with the TFS heads are that aftermarket roller rockers are required and an additional expense.

With factory ported heads, I use TEA out of Ohio. They are the company that developed the TFS heads. The TEA LS6 heads are usually within 5-10HP od the AFR 205s. The TSP heads tend to be 10-15HP behind the TEA's with the same cam. Peak flow numbers are great, but midrange is what makes a big difference.

On the 228R and a 346 or 366 engine, the 228 intake duration tends to get into an area of losing low end and starts to pull around 3500 or so. This can be offset by going to a 111 or 112 LSA, but this takes away some low speed driveability. With that said there are a lot of that cam out there with happy folks.

Hope this helps.
