Undercover ported stock heads? - Page 2

Mike Pearson · 10-08-2007, 12:36 PM

There is no doubt that allowing ported heads in stock will increase the cost to build the heads and engine.In super stock a good set of heads and intake cost around 8 to 10 grand. The issue with the CC size of the ports. If you use the SS volumes they are quite a bit larger than an actual stock port. The heads that I run have a intake runner volumn of 165 cc. The largest stock head that I have poured personally is about 157 CC. So you can see that if you use the SS head volumns the heads will be much larger than a stock head. Ported heads would not be a good idea for stock in my opinion.The move should be toward a more stock head. Even a rookie tech man should be able to detect heads that have been acid etched and shot blasted.

Enforcing the current rules is alot easier than people think. 98% of the bogus heads can be found using just the qualifying sheet. Any stocker that runs more than one second under has had some bogused up stuff done to the heads. Surely there will be racers attacking my comment but you can only lie to yourselves!!!!!!

There's nothing bogus in my cylinder head...

That's why I said 98%. I'm sure there are some combos that go one second under and have never even taken the head off.

If you get your heads from an enginebuilder that have alot of engines out there they seem to have a good feeling were that line is since very few get tossed for heads!

NHRA already is pouring the runners in stock. They did everyone at Indy and have done it before also.

i agree with greg hill use the ss spec, it is large enough for "comfort"

about 50% of runners poured have been found to be LARGER THANS SS SPEC...
of course there be a lot of heads out there used for $3000 doorstops if they do !!

No kidding! I don't know where that run came from. It's NEVER gone that fast. Must've been the good air that morning. Oh well, won't be going that far under again. That run bumped me right out of C/FS...
