Tell the girl to -----oh truck heads <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> .. take them to a good machine shop and get them ported. If you dont have the cash for a for port job then get them to do a pocket port job. You shouldn't need bigger valves till you open those ports up.

 

Port, polish, 3 angle valve job, 2.02 / 1.60 valves (in the stock seats) , double springs, push rods. That will get you to stage 1 and run in the $1700 min range new.

 

TEA stage 2 heads will cost you about 1800.00 plus core, probably will need a cam to take advantage of the full benifits of these heads.
