hks are a great choice, also crower has a new offering similar in price, but if you are on a budjet engle springs do the job just as well at a fraction of the cost. stay away from the ferrea spring for they require quite an amount of machining to the head.
-since your building the head any way my suggest the following:
1. hks cams (272 int /264 ext)
2. ats cam gears
3. mrs shimless bucket conversion (30-35% lighter valve train).
4. valve spring of choice (hks crower or engle depending on budjet).
5. ferrea oversize valves
-and if you dont have a competent machinist in you area familiar with 3s motors save yourself lots of trouble and send it to " the man" ChrisK in texas. he is a 3sgte expert and offers complete engine building services in addition to intake manifolds and fuel rails all of which are 1st rate quality.
he can be reached at
fj_chris@yahoo.com. for the cams and cam gears contact ats racing and ask for aron.
- i had work done by him. he knows what he is doin. satisfied customer here.
