what are your power goals?

94x4

I think that you may have that just a little backwards.

If you shave and/or plane the block as your first stage and slap the head on it with a regular gasket, you will then have higher compression with little or no modding to the head (except for maybe that cam,
baby! ).

Then, when you're ready for the second stage, that's when you use the "plate gasket" of proper thickness to bring the compression back down into tolerances specified for the "booster".

Yes just take the words "comp[ression up" and make it "compression down"
Well the block is more permanent and not so easy to just swap out. Rather do stuff to the head wher eI can jsut swap it out later. Not to knock ya 94x4 but shaving the block to get compression up and then using a "plate gasket" to get compression back down isn't now where near as good as shaving head and then later putting newer head on. "plate gasket" for less compresssion isn't a very good idea in the least especially large amounts of boost, just asking to blow it out the side.

My power goal is at least over 300HP with a heavily ported head and a little over 10lbs of boost.

94x4

The solid metal plate gaskets have worked for me (along with some heavy duty bolts to hold it together) and countless others that I am aware of, as has planing the block to really boost the low end compression to accompany the high end compression (there's intake and exhaust), especially with naturally aspirated applications, but to each his own.

I'm just trying to pass along a little advice/insight to those who may have an interest, you did ask.... Knowledge is a bottomless well, it's up to the individual whether or not they drink from it.

Good luck with the performance modding though, sounds like you're going to build something nice.

Thanks 94x4

Yea its already going well over wha tI priced in the beginning hah. I just found out there 8.5:1 specs is with a zero deck hieght, this is after they told me its was with stock block and head dohhhh. Well if you buy from them make sure you don't just take the sales guys word for it ask for the tech guys in the back building the engines. So with all that said I am actually going to block the deck to .010" to leave me room for future decking options incase I get a blown headgasket or whatever. And then just shave my head .020" and adjust the cam back with a adjustable cam gear. This leaves me with around 8.6:1 which should be okay temporarily as a N/A engine
While I build another head with the works done to it and slap it on with my turbo setup heheheheh

94x4

No prob', just glad that I could help someone else push the limits of their manufacturer based engine.

Remember to give us some pics as the project develops, 'kay ?!

What turbo are you going to use?

sonypete

Well not sure yet about the turbo. probally a used t3/t4 maybe a 14b mitsu, or maybe a KKK K26 or K27. I think when I first boost my engine only gonna go maybe 10lbs and usea smaller turbo. Not until I get a standalone will I jump to a bigger turbo and more boost. Don't want to blow this thing up right off the bat

94x4

Smart and I'd op for the T3/T4 for quicker spooling, even at lower psi.
