This tool is missing the hole to make it useful do I have to drill it out myself ?

Dear customer, hello, there have hole, please rest assured

Will this tool work for 350 Small Block Chevy?

Dear, sorry is not suitable for your car model.

Does this work on LS3 heads?

Dear, I’m very sorry, it doesn’t fit the LS3 heads, thank you for your attention

This will work with any cathedral port head and any LS square port head but will not work on the LS3 style offset intake on those heads. Your 2004 model is not an LS3 5.3. It is, however an LS and is a cathedral port. So yes. This will work. I use them often for on car spring swap jobs. If head is off engine, you will battle the head tipping due to pressure applied. Hope this helps.

Works perfectly! This is the valve spring compressor for SBC, LS and LT setups

Worked perfectly and took about 25 minutes to do all the springs on a head. DON'T waste your time buying the compressor to do 2 springs at once, they bind up and waste your time. This is quick press on and off using a 3/8 ratchet or breaker bar.I am sure after a few hundred springs with the tool, the aluminum would wear enough to be an issue, but for the price, that is a dumb thing to complain about.If you struggle putting the keepers back on, use a small magnet to pull them and place them, which is way easier anyways.

So easy to use

By far the easiest to use. It even works on the Gen V LTx heads. Unfortunately for the LS3 style intake valves, Texas speed is the only one to offer this style in a kit for both valves. But his is perfect for cathedral ports and Gev V. It's much faster than the $5,000 one I use at the machine shop.

Great idea for smaller head

Will not work for Chevy small block heads without heavy modification. And still at this point I'm assuming it will work. I still need to go buy a very skinny threaded nut. So if you're building a Chevy small block don't waste your time

Works like a champ

Professional mechanic and I thought it worked great. I can see that i am going to wear the tips off due to it being aluminum. I used an old rocker arm bolt instead of the supplied ones but that was personal preference

Great little tool. Easy to use. Just a bit of advise, use the bolt from the lifter it will make it work a lot better!
