If you shop around you should be able to buy them for around $1,400.
No matter what you do keep the port volume at or less then 290 cc.
A novice question. Are the Merlin 269 oval any better than a well prepped set of 781's? I was under the impression from another member on here that the 781's with gasket match and proper port work, llarger vavles etc will flow just as well as Merlin cast iro 269 ovals..just a question?
