which heads?
I have been having overheating problems in my L98. I have checked/replace almost everything and it still gets way too hot at times.
I have had it in the back of my mind for a while that the problem could be a head gasket, or even a cracked head. I didn't want to think about it because of the cost involved.
Anyway, if I do have to pull the heads off, I have decided that I would eventually do heads and cam. It just maybe sooner than later.
My question is, which heads to use. I have searched the archives and have decided either Edelbrock performer or AFR.
The AFR's I have read that they don't have fittings for coolant sensor/switches. I beleive they are also not centre bolt for rocker covers( although I may be wrong on this).
I use the car mainly for autokahnas etc, so I am more interested in torque than revs.
I am also thinking of using 219 cam, Superram and 1.6 ratio rockers.
So which heads for want I want to do?

AFRs for any future mods, especially a bigger bottom end.
But for the L98 itself, just as a bolt on, the Edelbrocks will work quite well and should be just fine for the SR and a 350.

If your #113 heads are OK, just have them ported and worked a little; then they will flow to over 400chp and should work well with that cam.
1 the port job will probally be in the $400-$600 range for porting only then plus a valve job seals and better springs you will be pushing $800-$1000 easy and like he said you can get 400 chp if you look around you can find a set of afrs used for that same $1000 or new for $1400-$1800 and they will make up to 520-550 chp with them + they will not be crack prone or warp prone as the factory heads are :cheers:

The condensor is slightly damaged, so that is reducing air flow anyway.
How hard is it to pull the front end off to get at the condesor and auxilary fan?
