i currently have 853 series heads i would like just a little bit more power bc im going to be spraying it. so i am not looking for a all out head. im currently making 385 through a flowmaster muffler. im getting a cutout welded on this week and getting it dynoed friday. i would like around 425 at the wheels with the heads so then i can spray a 125 shot safely and get to the safe 550 at the wheels. what heads would you reccomend on a very tight budget that would fit. there is a sponsor with some ported 241 heads for 500 would those fit?

Look into the PRC heads from Texas Speed

prc stage 2.5 5.3 heads go great with the ms3 cam. Atleast thats what i have herd.

+1 on the PRC heads. they dont brake the wallet. but if your on that much of a budget just get the ported 241 castings for 500 bucks. thats a good deal.

if u get the prc 5.3's make sure that they were made for the ms3 cause they wont work unless tsp sunk the valves i think

Either PRC 5.3 Stg 2.5 heads 62cc OR

PRC LS6 Stg 2.5 OR

PRC 215 Heads you can run any of those with MS3 without flycutting.

Let them know you are running the MS3 and they will recess the valves for better PTV

Good thread, I was also wondering the same for my MS3

How my car sits right now with just SLP intake and full exhaust with the MS3 it put down 412rwhp on stock 241 heads. My buddy is giving me some ported 5.3's

Looking at Texas Speed site, the PRC Stage 1 LS6 head has great flow numbers and is very reasonable cost, even with upgraded springs.

If the heads aren't from TSP, you might run into PTV clearance issues
