Absolute Speed
I waited over 6 weeks for mine .They make great hp. Now with a year and a half of trouble free driving on them I got more than my moneys worth and it was well worth my wait. Ofcourse If I wanted low power #`s and broken springs and possibly drop a valve seats I could have gotten a pair in a week. But I doubt I would have been as satisfied. But what the hell do I know.

Can we port match the new LSX intake to the heads? Lemme know. Later.
Trolls, what a dork.

Im sure Jay is gonna be really upset he isnt getting your business.
Sure jay could hire someone to answer his phone for him. I actually asked why he hasnt. He said he would rather deal directly with each customer even if there is a wait sometimes. This way they are dealing with the the owner of the business the guy who is working on there heads. Since he is busy porting all day there are alot of times he cannot hear the phone ring.
BTW his customer service is excellent!!! just ask a customer.
Good luck with whatever you decide to buy
Jays heads are the top dog. He has proven himself and the LS1 community that his heads are worth the wait. He tailors them to your specific combo so youre not getting an off the shelf standard head. Custom stuff takes time and hes a very busy man and he personally does each head, not a shop with many employees that touch them.
Well worth the wait.

As far as customer service, Jay also did work with me through numerous spring changes (since I couldn't make up my mind for 977's or 978's) ... I also sent him my cam and he did some extra work for me by putting it on his mock up motor to check P/V etc ...
Anyway .. would I have liked to have my heads in 4 - 5 weeks .. sure, would I have liked a little faster responce? sure ... did I catch Jay at a bad time .. YES ... alot of orders and moving a shop .... it happens ...
I know though .. when I get the heads, I'll have a quality product that JAY will back ....
Just my 2 cents ..

Not the news i was looking for
