Well I have my engine all apart, im replacing the valve seals, and was thinking about swapping some parts out while im in there. Looking at these as my options.

1. New HKS intake cam, either the 264 duration or 272 duration not sure what exactly is the benefit from one to the other a little help here??

2. Boost Logic's 2.5mm headgasket, Im still NA but would like to go turbo. Would i be better to wait to do both at once. Am I going to lose power while NA??

3. Also looking at removing the EGR system and adding some arp head studs.

I have 110 thousand on my 1992 SC300 now, would I be better off just waiting and rebuilding the engne and doing everything at once or do you think i should go with the above options?

Any input would be helpful, Thanks

increasing your head gasket thickness is going to lower compression, which will make you lose power N/A...

1. Not sure, up to you

2. Read jtucci's post

3. Not sure about the EGR, but you cant go wrong w/ changing arp bolts. w/ 110k miles, arp bolts will give ya a bit more security if ur reusing the factory ones.

You should have left it alone until you were ready to go turbo.

Are you doing the seals w/ the head on or off?

if you put that head gasket in there while na oh god your car will be slow literally a stock honda civic will beat u on 3 cylinders thats like driving my soarer with the charge piping completely off.... you would have a hard time pulling out in traffic

110,000 miles on a 92 SC is very good....Are those actual miles? Why is the engine apart in the first place if you don't mind me asking?

I have the engine apart to replace the valve seals, it was smoking really really bad from burning oil and it was also fouling out the spark plugs. I knew that the head gasket would change the compression just didnt know it would make that much of a difference in power.
Does anyone have the HKS cams on thier SC300 I would like to hear some feedback on them.
Is there any tuning required when changing the cams?

Thanks for the responses so far, keep um coming

And yes they are original miles.

for the NA head your only good option IMO is crane cams get a regrind from them
