THERE IS A PAIR OF WHAT IS DESCRIBED AS OLDER MODEL TWISTED WEDGE HEADS FORSALE. WOULD THEY BE WORTHWHILE AND WHAT SHOULD I PAY FOR THEM. ALSO WOULD I HAVE TO CUT THE PISTON TO INSTALL?

What cam and rockers are you running? You should be fine on clearance as long as the rest of your combo isn't too wild. Ask for pics so you can see what you're buying.

you shouldnt have to flycut anything. im running stock style pistons and twisted wedge heads with 1.6's and a stage 1 trick flow cam. and i dont have any clearance issues.

gspfunk

I agree, you could probably even run 1.7's if you wanted to.....

I would stay away from them, the TW's had valve guide problems on the "older model" versions.
it's fixed now, but was a problem when they first came out.

good artcl on TW history
