Heads only ? This is a wierd ? but what type of gains could be associated from doing a head swap considering your a decent bolt on car? I plan on running bone stock 243 heads with hardened pr's and dual vs's. However, I am a college student and therefore I am on a college budget (20 hours of work a week). I plan on running the tr224 or tr228 later on down the road but am kind of looking for the heads first. What do you think the benefits would be from swapping out crappy 806's that came on our 98 ls1's for the 243's and then going with the cam setup a few months later after part collecting? Also would you probably need a tune to compensate for the additional flow?
Just be patient,
wait and save and do heads and cam at once,
You will be happier in the end,
and its probably easier to do it all at once, then in two steps,
You just have to be patient enough to save up and do both,

Oh and to the above thread, I know that would be the best route...lol. Im just so impatient and sometimes feel I'll never get it done unless I buy it piece by piece. I suppose I could still go that route and by piece by piece and then install at once...hmmm...
Your crappy 98 heads arent as bad as you think. The only port difference betwene thoes and the 241 heads are the way theyre cast. The later casting methods produced a smoother surface in the ports.
As for your question, its way too much trouble to swap a set of unported heads. I just wouldnt bother with it and would save untill you could afford something better.

I'm doing the heads and cam right now. I wouldn't just do the heads and later on the cam. It's doing the work twice and it's a lot of work.
I can't believe the heads will only net 10-15 hp. The whole GM package is 70 rwhp or more. That would mean my LS6 cam is responsible for 80 percent of the total. I guess I'll find out.

I agree about waiting. I already have my 243 heads w/comp springs, Comp pushrods, ARP bolts, gaskets, LS6 intake and Stall on the way. I need to save up for the cam so Im waiting to tackle it all at once...prolly this summer.
