Hey Tech,
Thanks for getting back on here and posting.
I'm familiar with the idea of a gap being in the valve train valley,,,, just wish there was a way to get either in there to test for leaks. One time I did squirt some in the valve cover to see if it made a difference but nothing happened At least nothing blew up in my face LOL.

Now as for changing out the heads I'm not opposed to doing that either. I could sell the Dart heads for something and recoup a little of the cost. I'll be looking tomorrow for a number on them to see can I identify the intake runner.

I once had a Patriot head and a Pro-Comp (I think it was) flow tested and the dude was surprised at how well the Patriot head flowed and it did better than the other all across the board.

As for the air gap,,, being in the southern part of Texas (near Houston) we don't see a lot of real cold down here but your advise will be taken. I do have a Performer RPM as well from another motor I could pull and use.

As for the love thing,,, it may be looking up LOL,,, met a lady who really likes NASCAR and probably knows more than I do. But it's all in the first date stages so I'll have to see how that goes. At least I was invited to attend the race with her and friends next weekend so I must have passed some of the "He's an okay guy test" over the weekend ))

So I'll keep pondering all this and come up with a decision soon so I can move forward with the build. There is still plenty of other thing's to do but prefer to get one thing completed before moving on to another section.
