Heading into the home stretch!!

[Paul Workman]

It seems like "forever" since Lee and I pulled my hurt LT5 from the engine bay. The car will have been on jacks for 10 months, come June 30th.

Started out with what turned out to be a "melted" valve; according to the skilled eye of the machinist grinding the valves and seats.

Well, as long as the heads were off anyway, might as well port them, right? And, with a shining example (Pete's heads) to go by, might as well push the limit, huh? But, as Mark Haibeck once told me, "85% of the risk is in the last 15% of the porting!" How very true, it turns out. Welding a booboo on these heads takes a very skilled welder with the right equipment and rods. I feel I learned a great deal about porting these heads, but if I had it to do over, I'd think hard about just having them CNC'd by Pete's guy and be done with it.

However, it hasn't been all frustration. In the end I was able to incorporate nuance nuggets from Marc Haibeck's approach as well as Pete's on both the porting, the bowels, and relieving.

Anywayz...The last bit was to seal up a pin-hole in a weld in the lifter side of the runner. (Held 21" of Hg for over 15 minutes and never lost a bit!) Now both heads are sporting a very nice multi-angled valve job, been relieved, and milled. Time to put it back together!!

Some pix "along the way"...

Twazunt mah choice neither, ol' buddy!! (But, we had to optimize our chances on collecting from the insurance!:mrgreen:)

Haven't checked the long range forecast, but it will be July before she roars, and it doesn't look like snow is in the forecast either!!:rolleyes:

I hope it fires up and runs good without a hitch. I know its been a while on jack stands. I wasn't afraid to do my own top end porting but if I want to have the heads done then I'm just going to take it to LPE and pay the 29k and have them turn it into a 415 storker. zero miles on the od. brand new 564 rwhp with a warrantie for 2 years or 24k miles. for me that warrantie makes all the difference in the world and puts my mind at ease. I plan to take it to LPE within the next three years.
