Going w 067 and #17 heads
I got a pair of #17 small valve heads ready to install (and gone over) off Craiglist and am going with a Cometic .27 thickness head gasket (since the heads are I think only about 84 cc's).
Should give me close to 9:1 and run strong with 067 and 3.08 open gears or am I missing something? (The rest of the 354rotating assembly was rebuilt by prior owner w 60 PSI oil pump and good compression and doesnt burn any oil or blow by etc.)
Just want it to make decent power to 4000 rpm, the stock replacement #537441 was pretty much an 066 and grunted strong off idle to 2400rpm and then nosed over....just want to improve on that (perhaps it was worn valve springs holding the old cam back?). Have stock converter and peg leg.
