I'll call advanced inductions and talk things over with Phil. He can even make a set of 241 heads badass. Ask him about his high compression program for a 241 head.....

Those wont' work on a 346ci. Of the choices you posted, I'd opt for the PRC 225cc as cast heads.

Not the 317s. I'd do the 225's but if you don't plan on leaving this set up I'd find some 243's and hand port them if you have alot of free time. It'll be tons cheaper.

Then buy a set of heads that you can use on both setups. Possibly wait for Tony Mamos new Mamo Motorsports 220cc heads.

I got the ls3 heads on my 408 lol

xdanny510x

Wait lol i just did some researchin and totally left the tfs out of the question lol.. I remember back in the day they used to be alot of $$$ they run around the same as the prc lol thats why i didnt pay attention to them.. So i retract my previous statements

Yeah, 408ci is fine, but not a 346.

Thanks for choosing TSP for your camshaft! We've done tons of dyno testing with the MS4 camshaft so I'm sure we can put together just the right package for you!

As most of you know the PRC 227 is the ultimate small bore LS cylinder head on the market. The as cast is a cast version of that head. While it flows just slightly less than the 227, it is still without a doubt light years ahead of ported stock castings.

You get altered valve angles, thicker decks, 6 bolts incase you upgrade in the future, 2.065/1.60 valves & we can mill to your camshaft. For example 60cc chambers & your ms4! We can even sell them to you without springs if you want to move over your prc springs from you current setup to save $$$$

Considering a ported 241 isn't even a fair comparison....

Hope this helps!
