More pics













Hard to tell by the pics but the short side radius on the exhaust side can definitely use some work.

That hasnít been determined yet lol. Hoping for 7-800whp. The internals are capable of holding a lot more but Iím more worried about the sleeves shifting horizontally under high cylinder pressures so not sure if we will blow a head gasket at higher power than 800.

Well after my balls have finally reached the correct weightsnd size to grind on heads I have finally started the process of porting a spare D25 head before I do the W25 heads for this build.

Headgames burr ready to eat


After some porting








I have about an hour into this head so far. Had to stop for the day. Will finish it up hopefully by next weekend and post pics of the finished head.

Picked up the block today. Will post more pics detailed pics later but here it is. Lubricated the sleeves to keep them for getting surface rust and bagged the case halves.

Was able to grind away some more on the head today. Really time consuming, but Iím definitely not rushing it. I would consider myself halfway done on just the intake side of one of the heads.

I remember doing my own TGV delete and porting with a dremel back in the day, have a write up thread on here somewhere. When you start grinding away on some aluminum, it's not as bad as you would think. It's making the decision to start grinding/porting that is the hard part.

Will have a extra set of B25 head sometime soon, might just do the same thing.

You are correct. It took forever to gather myself and actually start grinding. Yeah aluminum is definitely a lot easier than cast iron. My biggest concern was to make sure I can get the ports consistent. Itís not easy, but somehow Iím pulling it off. I guess I see why itís so expensive to get a set of heads done, very labor intensive and time consuming.

I would also like to add that although aluminum is easy to work with, it takes the right set of tools. Over the past decade I have accrued all kinds of burrs, but not all are the same and if you started with a poor quality tool it will definitely put you off. I ordered another burr from headgames because I like my first one so much! Literally cuts through aluminum like butter(ish), doesnít dig in and get caught like some of my other burrs and leaves a super smooth finish. They may seem expensive but I think theyíre worth every penny.
