How much is the avereage cost and what are the typical HP/tourqe gains? [on stock heads]thanx.

Might wanna check the sponsors out to the right, different prices. If you have the funds, go with MTI, GTP, or LG.

If you tooking for the best bang for the buck:

Look into TEA, Absolute Speed, Patriot, etc.

Do some research and youll find out.

 

I have seen TEA and absolute heads do just as well as gtp and mti, more absolute heads than tea but tea seems to have an improved product {look I gave a little praise to tea everyone} I think LG carries absolute heads. I am narrowed down to absolute and gtp myself, one day I will call someone and order a set. Good luck with yours

 

Maybe so, but for the record, we all still hate you. j/k

 

What are the typical gains with stock LS1 ported heads and how much would it cost to have a mchine shop do it? thanx.

Typical flow gains at peak are around 50 cfm on intake and 30+ cfm on exhaust. This will gain around 20 to 30 rwhp and more with LT headers and cam change. Prices vary between $1200 and $2500 plus cores, best to check sponsors on sidebar for pricing>
