Just finished the most radical Honda I've ever done. This one is getting roller cams with .520" /.502" valve lift.
It took a lot a measuring, calculating, and trimming to get everything to fit.
In addition to the flow work and ridiculously large cam, it'll be seeing a lot of boost.
Customer is expecting this B series to produce HP well into the four-digit range.

Looks like I haven't posted anything for a little over a year so here's a BMW head I'm finishing up.
It got new guides, larger valves, and some basic flow work. It'll get surfaced once everything else is done.

I may be zeroing in on the problem. 🤔

Hey everyone, the shop is closed this week; I'll be out of town. I'll be back in the shop in Tuesday the 29th.
If you need to reach me, the best way is to text me.
I apologize for any inconvenience.

This is my customer's visual testimony to Evergreen timing belts sold on Amazon. Belt failed at 25k miles and destroyed 75% of his valves.
Turns out he didn't really save any money.

Another Ferrari 308 head repair after a factory sodium filled exhaust valve failure.
This may be the last one of these I do.
There's nothing fun about it!

Just a little single cam Honda head.
New Supertech valves, bronze guides, springs and retainers, and some basic flow work.
