Just curious how the flow of the regular (non-cnc) HTCC heads compares to stock heads? How do they compare to an average porting and polishing job of stock heads?

 

**Disclaimer: im no pro nor headporter nor anything like that. I only know what i have read**

It seems to me that SE Heads are one of the biggest rip-offs known to HD as a set of well prepped stock heads always kick the **** out of SE heads.

I think SBC has flow info on their site and i think HQ does also.

 

I don't like the balance from intake to exhaust flow on any of them to be truthful. We fix a lot of them and usually tell the guys to send in there old take off heads for porting and recoup some of their SE money on ebay.

 

In addition to what has already been stated (whick I totally agree with), it is VERY difficult to measure and properly set the quench on HTCC heads due to the funky crown on the pistons.

Forget them and send your stock heads out for professional porting. Your results will be superior!

 

I will agree with the others that these are somewhat of a PIA to set up, but if done right, the HTCC (not the CNC) heads with the HTCC pistons and a good cam set up for 10.5:1 such as the Woods TW5G will really make some power out of a 95" build. With that being said, there are not many HD shops that will take the time to do it right and you can aactually end up with a build that does not give you good performance. They are also pretty damn expensive , you can have your stock heads professionally ported for less than what you have in those heads.
