Any 243 casting head is just that, a 243 casting head. The castings themselves will all be the same. The difference in the ones from the Z06 cars is that they have Na+ filled valves.
Ok. Thanks corvette chris. just trying to learn about heads. i want to get some, but dont want to send the $ for trickflow or arf. Just looking for something that would give me around 30 extra HP with my cam that I have. I have the 241 stupid heads.LOL I thought about the patriot heads but dont know nothing about them yet. Trying to learn
it's been a while but I believe if I remember correctly once you buy a set of used heads, have them gone through, install new springs and milled for more compression you might be better off just buying a set of 243's from someone like Texas Speed. Depending on what you're looking for in performance, the main trick to the 243's is CNC exhaust ports and a good valve job with bowl work.
You want your heads and cam to work together so treat them as a package.
Thanks printman. Yeah, Now Im doing my home work on the patriot heads. im thinking the stage 2.5 heads..Im going to call them today to see what they say....

or just send your 241s to advanced induction. figure 350ish for stock 243 heads and 500-700 to work over. unless you are getting a free set of 243s easier to just buy already worked over ones.
Id buy the 243 heads and send them off to Total Engine Airflow....they have a stage I set up for the 243 heads that isnt terribly expensive. Check out their web site. Thats what Im planning to do with mine in the next month or so. Should be good for about 40 hp with the cam.

This is what I was going to do but after doing some research, buy the time its all done I might as well spend about the same kind of $ for a set of new Patriot Stage 2 Heads. They claim with those heads, Its possiable you can get up to 40 more Hp depending on the set up you have. So I think Im just going to go with the Patriot heads..

yea, I guess depending on how much they want for the 243 heads off the silverado. TEA quoted me 1100 for the stage I if I sent my heads into them which for me, is by far the most economical and bang for my buck

Yeah, Your one step in front of me. you have the 243 heads. I have nothing..LOL.. I just talked to TEA about 10 min ago and he said if I got the 243 heads and he did the stage 2 on it, then my cam would might be to big for the heads. He said he could do my 241 for about 1000, I said for me spending that kind of money, I dont know if i would be happy with the Hp results..So, Back to the Drawing board.. Dont know what to do. Might just stick with the Patriots..

just something to think about ...... sell your heads, off a Z they should bring atleast $500 and put the $1100 with it and you are close to a really killer set of AFR's or something

Now, I think this is what im going to do now. I was thinking about the patroit but called englandgreen and talked to jason. He said The 243 heads cnc'd will do better then the patriot. He said dont know why but patriot heads are a hit and miss. They experianced with them before. he said I cant go wrong with getting the 243 heads and getting them cnc'd.. So, back to looking for a good set of 243 heads..

The majority of the gains from any head work will come from a good valve job and some bowl blending. Last week, we bowl blended my 243 heads and lightly ported the exhaust ports. I paid $185 for a 3 angle valve job, cleaning, decking and assembling the heads.

Wow.. Those look nice.. Are they off your car.... Those look like Brand new..
Not to break into your thread, but I'd like to know where you can have the head work done for 185.00 dollars.
Actually some small shops with no overhead and older paid for machines can do that if they are paying workers min wage. Cheapest around here is around $225 and I'm sure they dont check much for that price and the better shops are at $350.

The machine shop I used is local.

This shop is probably one of the largerachine shops in Louisiana. This was my first actual experience with them though, as I don't know how much experience they have with LS stuff. They also have some of the nicest machines anywhere from here to Dallas, from what I hear. It may have been cheaper because I took them my heads bare and had brand new valves. When I originally got the quote from them, it was $155 for just the valve job.
