ok folks, this is where i sit now......

just finish re-torqued the head studs to 75ft/lbs- cause there was a good possibility the head-gasket is leaking on the inside (cant explain why, cause i used enough coppercoat) so re torquing the bolts may help. after running the car it still got hot- after running the car for 30 min it doesnt like to stay cool at idle either. but by reving to about 3000 it quickly subsides.---- may need to go to just a regular MLS gasket and say fuck the copper gasket(150bucks) and forget about the money i spent o-ringin the block(100bucks). this cooling issue is rather aggrivating.

attached my competition extention to the iceman intake-- big difference. noticed my knock numbers were lower then they normally are especially at idle after driving for a while. power gains as well. thinkin that the engine before was suckin in too much of that hot header air, probably why the numbers went down after the install, especially at idle. but the intermittent knocking is still bothering me

also hooked up my dual pod full a-pillar egt and oil pressure gauge the probe is about 3 inches away from the head (all that's left is hooking up the vacuum line to the oil pressure port- just need to pickup some brass fittings so i can also have the stock oil light working right). the gauge pillar looks nice. got rid of that stupid monster tach and shiftlight. dont really need them.

so i ran the car tonight and like i said more power with the iceman comp pipe. my egt read about 1000 degrees or just over when just cruisin (3-4000rpm), but gave it a couple of good 3rd 4th 5th gear pulls and the temps climb to around 1200+ degrees. it never hit 1300 as far as i saw. i also noticed that when i decelled the temp dropped sometimes to about 800 but not less.
What does this say about how im runnin- ive never had an egt or had to monitor one. does this mean im getting leaner? or does it naturally just run hotter on pulls cause more gas is being burned?
where does my temp range need to be?
PLEASE HELP?
