Wait til you see the pics of the head. I stopped by and dropped off a intake valve at the shop, took some pics of the heads and will post them tonight.

For $800.00 Valve job, reshaped the ports, cleaned up the combustion chambers, blasted the intake runners, and pulled out the cross threaded IH bolt out...this required him to reconstruct the area.....I don't know how the prior owner could have gotten the bolt in like that.

Only issue was the new lifters I bought on ebay are too tall and will not work...but my old ones are in great shape.

Before and after pics tonight.

seeing the quality of jerrys stuff and all the work he has put into each and every piece he has redone i would use his stuff .it might just be an improvement over the oem stuff .jmho

Well that makes a whole lot more sense. I was just scratching my head on why you would ever reuse head gaskets in your rebuild!

The IH bolt hole on the let was totally reconstructed as the bolt as broken off flush and in sideways, ca't really tell

Nice but I'd still open up the primary runner for all the hassle you're going thru.

LGAFF · 11-05-2010

I think there is plenty of flow as is....need to consider one side was over 40mm at the top

Both sides are ported

I am not drilling for oil or anti-freeze

When you consider the sie of Kevin's ports these are plenty big for a 350 LT-5:

What are you suggesting, that others have hit oil and/or anti-freeze?
