The best L92s on the market. These are goin on a 403 and headed to Germany. Bier country!!!! Or is it beir? Oh, who cares!?! LOL
NOTICE THE HUMP ON THE PORT ROOF IS NOT REMOVED!!!!!

Nice putry chambers

Heres where the magic happens!! Best exhaust ports out there.


And of course whats a good head without a cool logo?

 

I really like the way Richard seems to be able to get great flow numbers without carving the guide bosses down to nothing. Makes for good heat transfer from the guide and the quides wont walk on you. You could probably use those on a baby cam 403 and make 510/470 with 380RWT at 2200RPM amd 400 at 3k.

 

those look nice

 

prettty, other than that, i have nno input. whats the flow sheet look like?

 

A good tune can help also!

Really great product!Here is a few pic's of mine.Richard Rocks!

 

Good pic of the HS rockers. I went with the YT Ultralights for mine. More for reliability than anything else.

 

no doubt the best on the market, richard is the ****!!

 

Hey Ed, I think it's beer country!
Thanks for the props guys. Don't forget the same day service too!!

Richard do you sell them (L92heads) set up with the Harland Sharp L92 Rollers installed... I've seen where some slight machining has to be done for clearance reasons, and I just want the full package ready to install... PM me details and pricing if you do not want to post info... thanks...

 

I know you guys carry All Pros, but do you do CNC work on them or would you send them back to Bob? I have a set of their LS1 bare castings that I'd like to get finished.

 

vs. hand ported heads

 

Ed I'm wondering how well these heads would work on a 13:1-14:1 compression late model dirt track car? It would be carbed and on alky. Sounds like I might be building one as soon as they can dig the car out of the snow drift (there is supposed to be a garage left in there somewhere) up in the Rocky's of Colorado.

 

Early results say these heads like lots of timing to produce results. I ran 12:1 on my first iteration and could only run 26 degrees of timing. Reduced the SCR to 11:3 and now run 30+ degrees. I picked up considerable HP with the additional timing.

My $.02

 

makes me wish i took a pic of my L92's

 

also I woulden't say that wcch's exhaust ports are the best... actually mine are hand ported and the work looks like it was done on a cnc machine.....

 

Wow. Nice job! it so purty

 

Looks don't count. Flow quality does.

 

Let's see some flow number's. I'm a little partial to narrowing the guide bosses versus making the ports bigger. So let's see cc size of the runner, verses flow number.

 

Very true, Quality is much better than quantity.
