Cylinder Heads Help... Alright guys I have the 350 roller motor from my friend, I just stripped it to bare block... So now im getting the rotating assemly kit for a 355 setup and want to do 58cc heads on it running around 10.5:1 compression with flat top pistons...
My question is should I buy new heads with a cam kit or should I use the heads on the block and have them ported, I heard of this guy who does the heads who is well known on this site and im not sure who he or they are...
By the way im having the machine shop bore it .030 over to a 355... I figured a 383 bore would leave the walls to thin running into overheating problems...
So what should I do with heads and cam work? well mainly heads because Im most likely getting this:
Comp Cam
"XFI" 280 Hydraulic Roller Camshaft
GM LT1 & LT4 350ci 1993-96
Lift: .576"/.570" w/1.6 Rockers
Duration: 280°/288°
RPM Range: 2000-6000
