I was doing some searching on the site tonight, & i have come to realize that I have been having all the tune issues since putting on the newly refirbished G heads, & all... I remember that the eddy carb was significantly leaner when I ran it after the second phase of the mechanical upgrades. 

I had 13 inches of vac. prior to any of the mechanical upgrades.

Then phase 1, I did the rear main, the doulble roller chain & advanced the cam 4 degrees. 

I started it for a brief miniute with the oil, pan & front cover all torqued into place.

At this time the valves hadn't been adjusted for some time, & were definetly noisy... Maybe .018+.

The vac gauge read 14-15 at idle... Like i said it was brief maybe a minute.

After installing the G heads, I lashed the valves at the .015 that Isky specifies for the e-4...

I only had about 11 inches of Vac.  I chalked it up to the big valves & tighter lash amplifing the cam.

I now have been tinkering with the new road demon carb (525) (see other thread road demon vs road demon jr) and have come to a road block with the tuning... I can't get it to run properly.  I have noticed that after running it down the road that i can hear a whistle... I saw some posts on the site regarding others with vac leaks..

I think that it could logically be related to the head swap.

So, here goes the questions for my brainstorming:

Has anyone had intake gasket issues with the Bestgaskets??

I used KB copper coat on them with bone dry surfaces(brake clean).

I just sealed up every inch of this engine and would like to keep it as clean as possible... Not looking forward to spraying it down with carb clean & for heaven's sake oil of some kind!!  Any suggestions?
