340 with edelbrock heads overheating

hi everyone. sorry out of town for the week. no computer with me just my phone and i cant really see the writing on my phone.

I agree i never use sealant but the engine builder did , so i did i was just trying to copy him will not use any next time.

In the mean time I have spoken to the cam grinder told him what happened. I measured where the intake lifter is in comparison to the exhaust lifter when at exhaust tdc. the intake lifter is 4 degrees higher than the exhaust. The cam grinder said that is fine no problem. I have been searching on line as i have never run into

cam4.jpg his before and everyone seems to say i need to retard the cam so the intake and exhaust lifter are dead even at exhaust tdc.

I am really getting confused and a little lost on this now as the cam is possible out of time from the get go? Am I reading that right or is my cam grider correct in saying that i should be good? engine has about 600 miles in it since the rebuild.

I have uploaded the cam specs.


pistons are new, they have a part number on them i will look them up.
