Well this thing has been running like shit for a long time now so before I drive it off a cliff I have decided to do the top end, I will be ordering a new cam and lifter kit(timing chain, lifters, cam, gaskets and gears) I got the stock intake, the person who rebuilt this engine back i like 88 had put a drag intake on it and I think it has finally plug up. The Holly 650 will be replaced by a quadra jet 4 barrel. I haven't had a lot of time to look closely at the heads but my dad has been saying for some time that it has to be a burnt valve, and well cyl 4 has always had plugged up spark plugs so Thursday of Wednesday I will be pulling the heads(just to see what they look like) If I got a burnt valve I will just have that valve replaced, If I take the time and money to have the heads rebuilt that will be to much compression for the bottom end and I don;y have enough cash to replace the crank and all 8 pistons!
I will post as much pics as I can.

And the anti-freeze leaked in when I pulled the intake off!
