Hell, your a short block/heads away from having another engine. :lol:

To do a cam on a L99, that is what it takes.

Those DOD lifter are a ticking time-bomb in a performance application. I like to drive fast, race and rev high as this LSx pushrod engine can go. Pretty sure those lifters wouldn't have made it to 100k miles. :no:

If I deleted VCT, it would have been more parts. https://www.briantooleyracing.com/basic-vvt-delete-kit.html

If the car was a 6 speed manual LS3 car, I could have done a simple cam, valve spring swap and trunion upgrade.

The rockers were an extra on my build. Could have just upgraded the stock rocker trunions, but just went ahead and got the TSP roller tip pieces since I didn't have a way to press out the stockers. Plus, anything that saves me time is worth it. I just don't have a ton of free time right now. So them being already assembled is a plus.

Gonna do any port work while the heads are off??

For n/a they already flow well from all my reading. Exhaust port needs more work than intake side, if it has to be done.

One downside to L99 heads is I believe they have a heavier intake valve since they were not intended to rev as high as the LS3 because of DOD/AFM.

So I need to address that once issue for sure. Maybe get a set of intake valves at the very least.

Heads I've looked at are:

With my cam, these would flow about 377 cfm intake and 250 cfm exhaust I think: http://www.airflowresearch.com/260cc-ls3-cylinder-head/

Don't really think heads are worth it at this point.

Found weights on the TSP rockers..

Quote

To address the weight of the rocker. For the truest measurement we weighed both a stock rocker and our rocker without the trunions to take that out of the equation. Just bare. 

The overall weight difference between the two rockers is 11 grams.

The weight difference over the nose is only 8 grams

The weight difference between a tool steel retainer vs a titanium retainer is 5 grams.

I hope this clears some things up.

So I'm reading stock GM, CompCams and BTR trunions are sometimes prone to premature wear.

Less than 1,000 miles on these? :eek:

Your tsp rockers use the exact same bearing.

Negative. Tear down those non-stock parts on the Fox in to a pile and you got me beat by a long shot! ;)

The install is the hard part. :meh:

Get heads or no?

Got my eyes on Trick Flow, but not sure if the valve orientation will cause PTV with my cam and VVT. :shrug:

Stock with GMPP CNC LS3’s? But only 10% increase?

Hmm...

Dang you and your question posts.  I keep seeing updates to this thread and I click on them hoping, PRAYING that there will be some dirty tool and busted knuckle stories but nooooooooooooooooooooooooooooooooooooooooooooooooooooo.

Someone answer his latest round of questions about whether or not to get head and THEN maybe we can see some install pics!

If mine I'd home port them.   I'd do so because the heads will be removed for other work, and replacing them is probably not worth the expense.

However, what are your long term goals?

I'm in no hurry since @Mike's track day isn't happening.

I'm going to stock pile parts that'll get me to my hp/et goal and then put it all together at once.

Did you not see @Mike's attempt to port his stock LS3 heads?

He has much better skills and eye-hand coordination than I do, so head porting for me would be a quick way to trash a good set of LS3 heads that I could sell to recoup some cash. :yes:
