Selling my M113k ported heads. They have been fully gone through and include a brand new valvetrain with larger intake valves. These heads have been done by the same person that has ported Hadilaw's, Brooke's, etc heads. Jerry from Eurocharged also has experience with them and claimed they made very good power. Wouldn't surprise me if they make 50hp's if not more. I have over $4k into them.

Letting them go for $3500 shipped.

 

Here are some more detailed pics.

BTW - stock heads flow about 260 cfm intake and 160 cfm exhaust. These flowed 295 intake and 194 exhaust. A ~13% gain in flow on intake and a ~21% gain on exhaust.

 

Who did the work ? Did you ever install them / use them ?

In short:

ExoticMetal (Brooke)/Shardul is who I purchased them from. The person that did them is very reputable in the industry but I have been asked not to share it. They may pop into the thread and discuss.

I didn't install them but there are a number of members on the board that have them. More so than any other ported head.

 

SOLD.
