help choosing a head gasket
I'll straight up admit I'm way out of my league and this is all a bit daunting. I'm reading up from articles on the net but thought I'd check in for some actual hot-rodders experience
I've got a '90 L98 GTA and have purchased some AFR 180CC 919 heads and the xfi268 comp cam. Block is standard. It's a speed density car
Grateful if someone could guide me about what head gasket I'll need for decent drivability compression.
Don't think it matters but car will have a heavily ported TPI setup (siamesed runners), 25 lb injectors and a 52mm TB.
If you need anymore info, let me know
thanks

Re: help choosing a head gasket
Call GM an order a Hi Performance head gasket for an 87-91 Corvette which is .028 thickness. It will boost the compression. If they don't have it then call TPIS. Dont use Fel-Pro.
