I'm just about ready to start building up a few sets of large oval port, open chamber BB Chev heads. I have four sets to start, and they'll be set up as the following:
*Castings cleaned, mag'd and inspected. Completely deburred, sharp edges broken, water passages cleared of casting flash, etc.
*All new bronze liners honed w/ correct stem clearances
*NEW 11/32 stem severe duty stainless valves 2.19 or 2.25 intake/ 1.88 ex
*NEW 1.55" hyd roller or flat tappet, super clean silicone steel "PacAlloy"type valve springs
*NEW Chromoly 10* steel retainers and locks
*NEW 4140 studs and guide plates
*Custom 5 angle intake valve job, radiused ex (45* or 50*)
*Valve heights equalized
Fully assembled w/ proper installed height, chambers cc'd (not matched, checked for volume for compression calculation) and fresh surface on decks.
If anyone might be interested in a set of these, PM me.
I'll have flow numbers available on the first set I do, so we can put to rest any misconceptions on how well these heads will work on engines below 500ci and operating at or below 6000 rpm. These will be quality assemblies mostly with American parts, not cheap Chinese crap.
