Heads
Okay, i'm trying to decide what heads to go with, I have a set of 241s that I was going to send off to Advanced Induction. But I could also buy a set of Trickflow 215s. I'm going with a small 226/232 113 LSA.

Although both are good choices, i would get the TFS 215s from a head assembler like Total Engine Airflow so you can look at valve spring and other options. Trick Flow specifies roller rockers if the standard bronze valve guides are used, so if you want to use stock rockers specify powdered metal valve guides. Also consider having them mill the heads to increase compression depending on your application.

I have herd some nice things about AI. however,it's a stock ported head. The AFR and trick flow heads have a better chamber design,thicher deck and a better cast. I have ran two sets of stock ported heads and after each one i went to a AFR and a trick flow head. each time i made great gains over the stock ported heads that were worth the money spent. You get what you payfor.

You do get what you pay for. The casting matters very little insofar as performance and longevity are concerned. It is the machine work applied that makes the difference. When you buy an aftermarket casting, a great deal of your $ spent goes towards castings & parts. When you pay for high end machine work alone, all of your $ goes towards what actually makes a difference.
Would highly suggest you do not buy a cam before buying heads. It has nothing to do with 'flow matching' or other talking points, but physical compatibility. Good luck with your project!
