I wouldnt use them exclusively if they werent. If you call them, talk to Tom Allen and tell him you got their name from me. They arent the fastest, but worth the wait! And yes, they are good.
There are a lot of places that does porting for aluminum heads but not to many that wants to tackle porting factory cast iron heads if that is the actual question you were asking? I have been waiting 2 years for the guy I use to get healthy again after breaking his back! :eek2: So glad he didn't get paralyzed when he did that, not only a excellent head porter but a great guy. ray: He is finally slowing getting back into working again. :TU: Before the accident he didn't care if the heads were aluminum or cast iron or what brand they are, he would make any of them work VERY well! Henry has worked on the top fuel BBF heads that he got to flow 640 CFM intake and 320 exhaust as well as some work on the Edelbrock headed N/A 1,000 HP Pontiac among the many other accomplishments before the operations and bad luck. When he gets caught up with the jobs I have lined up for him and if he wants more work I'll start a thread here for him to see if anyone is interested in having him do any work for them. o No: Derek
How about that one guy (the best head porter around) He's Related to Bell. A rather testy guy who is famous around here for most entertaining porting threads
