From what Ive seen my guess would be about 40 more to the wheels w/ a decent set of heads and a cam that size. That would be on an m6 car. Your stall will throw the hp #'s off a little.

Looks like the MagicStick V.3....get yourself a slighly bigger converter or have your current one restalled. You will get more power all around.
With aftermarket heads you would have to find out if they will clear without flycutting the slugs or having custom relieved pistons. I voted fully ported 241's. I run the same thing, only I am milled for a few more compression points. .030 to be exact. Wouldn't recommend doing that with the MS3 though unless you check your clearances.

What's your budget? Everyone of course will say aftermarket or fully ported.
If it was me and I was doing 'em myself, per head I'd spend one week after work and weekends and fix 'em up really nice, then take 'em to a machine shop and have them milled to bring up the compression ratio.
For the price of porting tools and minor machining I'd have some flow numbers that aren't bad for $200 invested. Just search and print tons of ported head pictures and take your time.
Home ported is still better than stock heads/cam, which ALOT of us are doing and making good power on.
I'm not fuggin' with heads though, I'm saving and going straight for the D1 Procharger. ~Joshua

yeah i heard a 2 inch intake valve in a stock head brings up the flow. so i think i am going to get some bigger valves and just polish the heads with some mild pocket porting. that should flow around 275 ish. so id be happy.

just watch how big of cam you put in and how much clearance. A buddy of mine had a friend who put a big cam in with stock heads and didnt check the clearance after all was done the pistons slapped the valves and knocked a hole in every piston and bent every valve costly mistake........had to rebuild.
