DeTomaso Mailing List: May 99, Message #181

hi "mary"  ;~)

thanks for the info - i guess i'm doing all rite - my set-up i'm getting is
similar, except i have double, not triple springs, the guides are iron, & i'm
not sure yet, whether the chambers will need to be cc'd - they're getting
czeched.  everything else will be the same as what you have.  it's costing me
$775 (delivered), & i'll still have my 4v open-chamber heads...

	Doug I'll share my experience in Nov of '92 for comparison purposes.  I
am
	confident that it could have been done for less or you may forgo a few
of
	the extras.  I was surprised how things added up.

	I swapped my tired open chamber heads plus $200 for a tired set of
quench
	heads.

	Heads w/exchange                           $200
	Install 8 hardened exhaust seats    $100
	Machine heads for screw in studs    $100
	Install Bronze valve guides                $125
	Match ccs in head  (58cc)                  $80   (Required decking
surfaces
	.045)
	Stainless Valves and 3 angle grind    $235
	Guide plates                                            $21
	single groove keepers                                $4
	Rocker Arm Studs                                    $29
	Machine spring seats for triple springs    $32
	Spring retainers for triples                           $26
	PC Valve seals                                            $19
	Total                                                        $971**


	**Excludes cost of springs which were part of cam kit and value of open
	chamber heads.
