It's a recent rebuild. Not a lot of miles on the rebuild but a few years. Just thinking on "the next thing"Lets get a little deeper into this, original oil pan gasket? Timing cover/water pump gaskets original? A lot of miles? Any seepage?
If you feel nothing else needs attention then swap the heads in-car.

I'm staying at 10lbs, real happy with the griptec pulley even on the 6 rib I'm not slipping but I don't think these e7 heads are gonna let me hit my 400hp at the crank goalTranslation:
Contemplating boosting theout of this thing and wonder how much ass-pain the head gaskets will be.
True, but the power is the goal. Lower restriction but better power with more flow. Any smaller pulley and I have to dive back into the rabbit hole with different crank pulley and more ribs. I might be able to get there with longtubes and 1.72 rockers but by then I'm already into some cheap aluminum heads.You will lose a couple lbs of boost with better flowing heads with the same pulley.
True.Engine Masters is a great source of info on what works and how it does it.
You can make the same power with good heads on less boost, kinda have'n cake all day long.
Same power, less boost, parts last longer.......well unless you get greedy.
Just the ramblings of an old man.
absolutely true!!True.
But...
You can make the same power as the good heads with boost as the "bad" heads just by turning up the boost a lb or two.
They made 25 or so more hp with the good heads N/A over the baseline heads, but it only translated to 18 or so more hp when boosted.
Yes the boost was lower due to efficiency, but turn up to boost to the previous level, and the hp advantage went away.
It proved that "bad" heads are not that bad when using boost.
Explain how the engine is "less stressed'absolutely true!!
but my point is 'same power on lower boost plus the engine is less stressed, it should last longer,
boosting stock heads is great....but the quest for 'more' is undeniable.
Easy, think about it.Explain how the engine is "less stressed'
It is making more hp.
What is the best oil to use? LOLEasy, think about it.
Nevermind, it's one of those infinite discussions.
Everybody is right to a degree.
Right. Heat is the answer. The more air you cram in there and compress the hotter it gets. The heat and addition cylinder pressure is what is tough on an forced induction engine.Well, it's not just boost, it's also heat. It's obvious when the ecu starts pulling timing due to IAT being too high. The charger gets that air hotter and hotter and without an elaborate cooling process (which I don't have) you lose power. More pulley, more heat, less dense charge, less timing. Better heads, less pressure, lower temps, power gain is 2 fold.
