First off Call PES and order a set of bolt in lumps And Hit your nearest Bolt supply place get 3 pipe plugs & 3 alein Head Bolts grade 8 and It will cost you less then 100 bucks. The lumps cost 60. bucks and a few bucks more for shipping.(shipping cost depends on where you live) The bolts & pipe plugs should only run you about 10-12 bucks maybe even less.
To install the bolt in lumps First Off the bolt boss needs to be removed. Then the head will need to be drill out& tapped at the top of the boss(head where the head bolt used to stop)for the pipe plugs.Then a area will need to be drilled on the bottom side of thehead for the retainning Bolt will go to Bolt in the lump. Then one of two things will need to be done to the lump or for it.
1) you will have to tapper the Lump or
2) make a tappered plate to bolt into the intake itself.
3) so no matter which way you may go about this It all has to be then blended together.
Now as for what this lump port does It makes the port smaller But increases air speed.(meaning higher flow numbers Makeing for a much better breathing head= better over all performance.)
The 270 seems a little more to most for a daily driver. But you will need to step up the stall speed if you're running a At tranny. If you have another head to start on and the cam hasn't all ready been installed yes it would be in you best interest to have the head built to match everything that you are plaining. but you are on the right track in your plains. }[oooooo]
