Well I need to change my valvesprings so I have decided I will just replace the heads as well. I have a 224/228 comp cam with 581/588 lift 114 lsa+1. Motor is an LS1. Budget is $2000. What heads do you go with that match up with best with said cam or do I need a different cam as well? I have an LS6 intake as well, considering going to a Fast.

I would get some trick flow fast as cast for around 1600. If you can get some 243s for cheap you can send them to AI or TEA. I would go with the trickflows myslef.

Ported 799/243's for the win on this one! Bought my 799's bare seeing how tea doesnt use the stock valves, springs or retainers. Bought my 799's for 195 shipped bare and a 1300 dollar porting puts them at 1500ish bucks, leaving you money to get gaskets, bolts, etc.

So the PRC LS6 stage 2.5 or stage 3 heads would be a good way to go?

If you.don't already have ls6 heads to send out for porting get the trickflows. IMO

If you do decide to get the tfs 220's id give tea a call and ask how much it would be to have powdered guides installed, unless you already have aftermarket rockers

Can you elaborate, dont really know much about powdered guides. Dont have aftermarket rockers btw.

lemkerailroad

when getting a set of heads does it matter if you get new rockers

why wouldnt you use the stock set that came with the engine

they are 1.7:1 from the factory.....right?????


i can see where alot of the aluminum rockers would break at the neck or base,
but is this doing it because its liter material being used??????

most after market non gm heads use bronze valve guides ,which tend to wear faster if used with stock gm rockers.trick flow offers a powder metal guide like the stock gm heads which allows the use of stock gm rockers.I recommend rebuilding you stock rockers if you reuse them.I think the trick flow 220 head is a good head for the price ,but check out some TSP PRC heads and maybe get them at a X-mas sale.
