Flat tops. Yet I have an engine code H on the block. Everything else said L69 and I had originally thought that it was an L69.
Then I popped the heads off today and see the relief valves and for some reason I didn't think there were supposed to be any.
I did a search on the board and lots of people said H engine code is LG4 and nobody disagreed.
That's why I thought I'd double check. Not that I could do anything about it..........
I was a little surprised about the amount of carbon in there, but the cylinder walls look very good. The #7 cylinder I was worried about because I had a spark plug that had been deformed once in that cylinder, but it looked perfect.
So I am slapping on some World Torquer 305 heads, some SLP headers, a 3" cat and a 3" Hooker cat back. I already have a Comp Cams XE 262, performer carb, jacobs pro-street ignition, roller tip rockers and some other junk.
This thing should really wake up with the new breathing capabilities huh?
